Answer:

Step-by-step explanation:

1) If you really meant X^2+12=40, then this simplifies to x^2 = 28, and therefore x = ±√28, or x = ±2√7.

2) If you meant X^2+12x=40:

a) Take half of the coefficient of x:  that would be (1/2)(12), or 6.  

b) Square this result, obtaining:  6² = 36

c) Add this 36 to x^2 + 12x + 40, and then subtract it:  We get:  

x² + 12x + 36 - 36 = 40, or x² + 12x + 36 = 76

We have to add 36, as indicated above, to "complete the square."

Answer:

X = 9.2

Step-by-step explanation:

You have to use the pythagorean theorm, which is a squared + b squared  = c squared. Looking at the triangle, the vertical line is 6, and the horizontal is 7.

6squared + 7squared = c squared

85 = csquared

Take the square root of both sides to get rid of the squared on the c.

sqroot of 85 = 9.2

Answer:

a) The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:

8x = 32

b) Nina delivered 4 times as many papers the second week as the first week

Step-by-step explanation:

From the question, we are told that:

Nina delivers newspapers.

In the first week, she delivers 8 papers.

In the second week, she delivers 32 papers.

Let x represent the number of times

The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:

8paper × x = 32 papers

8x = 32

Solving for x

8x = 32

x = 32/8

x = 4 times

Therefore, Nina delivered 4 times as many papers the second week as the first week

Answer:

see explanation

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

A

There is a common difference d between consecutive terms , that is

d = 5 - 2 = 8 - 5 = 11 - 8 = 14 - 11 = 3

Thus the sequence is arithmetic with a₁ = 2 and d = 3, then

[tex]a_{n}[/tex] = 2 + 3(n - 1) = 2 + 3n - 3 = 3n - 1

[tex]a_{n}[/tex] = 3n - 1

B

There is a common difference d between consecutive terms , that is

d = 11 - 9 = 13 - 11 = 15 - 13 = 17 - 15 = 2

Thus the sequence is arithmetic with a₁ = 9 and d = 2 , then

[tex]a_{n}[/tex] = 9 + 2(n - 1) = 9 + 2n - 2 = 2n + 7

[tex]a_{n}[/tex] = 2n + 7

Answer:

so for question a the ans is 3n-1

for question b the ans is 2n+7

Step-by-step explanation:

using the formula for arithmetic progressikn(a.p) a +(n-1)d, u use this formula because it has a common differnce

a=2, where a is first term or t1

d=t2-t1=5-2=3m where d is common difference

replace the values in the formula

2+(n-1)3

2+3n-3

3n-3+2

3n-1, this is the formula for the nth term

it will be 3n -1

if u try it

3(1)-1=2

3(2)-1=5

3(3)-1=8

3(4)-1=11

3(5)-1=14

using the formula for a.p, a+(n-1)d

a=9, because it is the first term

d=t2-t1=11-9=2

replace the values in the formula

9+(n-1)2

9+2n-2

2n+9-2

2n +7,this is the formula for the7th term

if u try it

2(1)+7=9

2(2)+7=11

2(3)+7=13

2(4)+7=15

2(5)+7=17

Answer:

The slope is -4/5. Hope this helps!

Step-by-step explanation

To find the slope- Look at both points, Count how many units it is from the other point. Count how many units down and how many units right. Then its rise over run. So how many units down would go ontop of how many units right. This means the answer should be -4/5

Answer:

93 3/5

Step-by-step explanation:

Total bushels to sell = 140

Average sale per day = 15 3/5 bushels

Total change in the number of bushels sold after 6 days ;

Average bushels sold per day * Number of days

15 3/5 * 6

(78/ 5) * 6

468 / 5

= 93 3/5

Change in number sold after 6 days = 93 3/5

Answer:

16

Step-by-step explanation:

If x = 3 and  , y = 2.  

2 x 3 = 6  and 5 x 2 = 10.

10 + 6 = 16

The value of the expression 2x + 5y when x = 3 and y = 2 is 16.

We have to determine, the value of the expression 2x + 5y when x = 3 and y = 2.

According to the question,

Expression; 2x + 5y

To determine the value of the expression calculation must be done in a single unit following all the steps given below.

The value of expression 2x+5y,

When the value of x = 3 and y = 2,

Therefore,

[tex]= 2x + 5y[/tex]

Substitute the value of x = 3 and y = 2 in the given expression,

[tex]= 2(3)+ 5(2)\\\\= 6 + 10\\\\= 16[/tex]

Hence, The value of the expression 2x + 5y when x = 3 and y = 2 is 16.
