Answer: 17

Step-by-step explanation:

Given: [tex](ax+b)(2x+3)=20x^2+44x+21[/tex], where a and b are two distinct integers.

First simplify left hand side as

[tex](ax+b)(2x+3)=ax\cdot \:2x+ax\cdot \:3+b\cdot \:2x+b\cdot \:3\\\\=2axx+3ax+2bx+3b\\\\=2ax^2+(3a+2b)x+3b[/tex]

Then comparing left side and right side

[tex]2ax^2+(3a+2b)x+3b=20x^2+44x+21[/tex]

we get 2a = 20 (coefficient of [tex]x^2[/tex]) , and 3b = 21  (constant term)

⇒ a= 10 and b= 7

Then, a+b= 10+7=17

Hence, the value of sum a+b is 17.

Answer:

[tex]\displaystyle \lim_{\Delta x \to 0} \frac{(x+\Delta x)^2-2(x+\Delta x)+1-(x^2-2x+1)}{\Delta x}=2x-2[/tex]

Step-by-step explanation:

We want to find the limit:

[tex]\displaystyle \lim_{\Delta x \to 0} \frac{(x+\Delta x)^2-2(x+\Delta x)+1-(x^2-2x+1)}{\Delta x}[/tex]

We can expand the numerator:

[tex]=\displaystyle \lim_{\Delta x \to 0} \frac{(x^2+2x\Delta x+\Delta x^2)+(-2x-2\Delta x)+1+(-x^2+2x-1)}{\Delta x}[/tex]

Simplify. Combine like terms:

[tex]\displaystyle \lim_{\Delta x\to 0} \frac{(x^2-x^2)+(-2x+2x)+(1-1)+(2x\Delta x+\Delta x^2-2\Delta x)}{y}[/tex]

The first three terms will cancel:

[tex]\displaystyle \lim_{\Delta x\to 0} \frac{2x\Delta x+\Delta x^2-2\Delta x}{\Delta x}[/tex]

Factor:

[tex]\displaystyle \lim_{\Delta x \to 0} \frac{\Delta x(2x+\Delta x-2)}{\Delta x}[/tex]

Cancel:

[tex]\displaystyle \lim_{\Delta x\to 0}2x+\Delta x-2[/tex]

Now, we can use direct substitution:

[tex]\displaystyle \begin{aligned} &\Rightarrow 2x+(0)-2\\ &=2x-2\end{aligned}[/tex]

Therefore:

[tex]\displaystyle \lim_{\Delta x \to 0} \frac{(x+\Delta x)^2-2(x+\Delta x)+1-(x^2-2x+1)}{\Delta x}=2x-2[/tex]

Answer:

2x-2

Step-by-step explanation:

let d = delta x

lim as d goes to 0  ( ( x+d)^2 - 2(x+d) +1 - ( x^2 -2x+1))/d

Expand the term in side the parentheses

( ( x+d)^2 - 2(x+d) +1 - ( x^2 -2x+1))

x^2 +2dx +d^2 -2x-2d+1 - x^2 +2x -1

Combine like terms

2dx +d^2 -2d

Replace

lim as d goes to 0  ( 2dx +d^2 -2d)/d

Factor out a d

lim as d goes to 0  d( 2x +d -2)/d

Cancel the d in the numerator and denominator

lim as d goes to 0  ( 2x +d -2)

Take the limit of each term as d goes to zero

2x +0-2

Answer:

myrna farm has 265 and the commercial farm 500

Step-by-step explanation:

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The farm that has the most fruit trees are commercial farm.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Given that Foster's Farms has 53 fruit trees on their land. Myrna's Farms has five times as many fruit trees as Foster's. Therefore, the number of trees on Myrna's farm is,

Number of trees on Myran's farm = 5 × Number of trees on Foster's farm

                                                       = 5 × 53

                                                       = 265 trees

Since the number of trees on Myran's farm and Foster's farm is 265 trees and 53 trees, respectively, while the number of trees on the commercial farm has 500 fruit trees.

Hence, The farm that has the most fruit trees are commercial farm.

if u like leave a thank

Answer:

the variable x=12.5

Step-by-step explanation:

so first you will insert 29 to the equation

29= x2+4

now you subtract 4 from 29

29-4= 25

since you are multiplying you have to do the opposite operation which would be division so now divide 25 by 2

25/2

now insert your answer

h(12.5)=(12.5)2+4

h would be considered 2.32

Answer:

2 cups of sugar:3 cups of flour

Step-by-step explanation:

Because there are 2 cups of sugar and 3 cups of flour used, you can represent this with a ratio - 2 cups sugar:3 cups flour.

Because 2:3 cannot be reduced (it is in its simplest form), this is the final answer.

65 miles per hour / 60 minutes per hour = 1.083 miles per minute.

126 miles/ 1.083 miles per minute = 116.03 minutes

Rounded to nearest whole number = 116 minutes.

Answer:

116 minutes

Step-by-step explanation:

speed = distance/time

speed * time = distance

time = distance/speed

time = 126 miles / 65 mph

time = 126/65 hours

time = 126/65 hours * (60 minutes)/(1 hour) = 116 minutes

How do you find a function for this story?

On your first day of work, you get $1. On your second day of work, you get $4. On your third day of work, you get $9. On your fourth day of work, you get $16. It continues this way for 30 days and then once you’ve completed the 30 days you receive a completion bonus of $500000.

No. of days Amount earned

1 1

2 4

3 9

4 16

. .

. .

. .

30 500,000

To find a function to the story

Let

No. of days = d

Amount earned = A

When,

d=1, A=1

d=2, A=4

d=3, A=9

d=4, A=16

It can be seen that amount earned is a square of the number of days

Therefore,

The function for the story is:

A=d^2

When d=30

A=30^2

=30*30

=900

Adding the total earnings for 30 days=$500,000

That is

1+4+9+16+25+36+49+64+81+100+121+144+169+196+225+256+289+324+361+400+441+484+529+576+625+676+729+784+841+900=500000

Answer: $ 532

Step-by-step explanation:

Given: Ramona works in a clothing store where she earns a base salary of $140 per day plus 14% of her daily sales.

She sold $600 in clothing on Saturday and $1200 in clothing on Sunday.

To find : Earning in two days.

Total sales she did in 2 days = $600+$1200 = $1800

Then, her total earning for 2 days = 2 x( Base salary)+ 14% of (Total sales)

= 2 x ($140) + (0.14) ($1800)

= $(280+252)

= $ 532

Hence, she earned  $ 532 over the 2 days.

Answer:

$532

Step-by-step explanation:

Ramona worked for two days. So she would have already earned $280.

And she also earns 14% of $600 from the first day, and 14% of 1200.

14/100 * 600/1 = 8400/100 = $84

14/100 * 1200/1 = 16800/100 = $168

$280 + $84 + 168 = $532

Altogether, Ramona earned $532 in the total of two days! Wow that's more money then I get per month lol.

Answer:

the answer is -4

Step-by-step explanation:

-16-4g=6g-6g

    +4        +4

you add the -4g to both sides by changeing it to positive  

then you have -16=6g-2g

then you go to the right side of the equation and solve, 6-2 is 4 then you have

-16=4g then you divide on both sides

-16 divided by 4 is

-4

Answer:

[tex]\Huge \boxed{g=-4}[/tex]

Step-by-step explanation:

[tex]-16-4g=6g-6g[/tex]

Combining like terms.

[tex]-16-4g=0[/tex]

Adding 4g to both sides.

[tex]-16=4g[/tex]

Dividing both sides by 4.

[tex]-4=g[/tex]

Answer:

Solution : 29

Step-by-step explanation:

As this is an equilateral triangle all sides present are congruent.

3x + 8 = 5x - 6 = 2x + 15

3x + 8 = 5x - 6

- 2x = - 14,

x = 7

And hence one side length will be say 3(7) + 8 = 21 + 8 = 29 units. We can double check this solution by substituting x for other side lengths. Remember that all the side length have an equal measure.

5(7) - 6 = 35 - 6 = 29 ✓

2(7) + 15 = 14 + 15 = 29 ✓

So, the answer would be 40% and 60%

╰(*°▽°*)╯

Answer: p lies between 50% and 55%

Step-by-step explanation: if 9 is p percent of 17, then p is a number between what numbers

9 is p percent of 17

Lets make the equation for the given statement

9 = p percent times 17

p percent is p /100

Lets solve for p

multiply both sides by 100

Divide both sides by 17

p= 52.9

Hence we say that p lies between 50% and 55%

Answer:

Step-by-step explanation:

f(x) = 6x^4 + 4x^3 - 5x^2 -2x + 1

The highest power will describe the end behavior

f(x) = 6x^4

Let x = -∞

f(-∞) = 6 * (-∞)^4 = 6* ∞ = ∞

As x goes to -∞  f(x) goes to ∞

Let x = ∞

f(∞) = 6 * (∞)^4 = 6* ∞ = ∞

As x goes to ∞  f(x) goes to ∞

Answer: $70.50

Step-by-step explanation:

30npm x 125m = 3750 nails total

3750/40 = 93.75, meaning you will need 94 boxes to complete the fence

94x0.75= $70.50

The cost in dollars for the nails to build a fence 125 meters long will be $70.31.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

A fence is 125 meters long if it requires 30 nails per meter. Then the total number of the nail will be

⇒ 125 x 30

⇒ 3750 nails

Assume that 40 nails are sold per box. Then the total number of boxes of nail will be

⇒ 3750 / 40

⇒ 93.75 boxes

The cost of $0.75 per box. Then the total cost of nails will be

⇒ 93.75 x $0.75

⇒ $70.31

Then the cost in dollars for the nails to build a fence 125 meters long will be $70.31.
