Answer: 2(4 + x)
Step-by-step explanation:
i just multiplied across the parentheses. we can rule out the first option, because it would multiply out to be 8 + 4x.
the second option is the one that i calculated second, so i knew that i could rule out the last one my default.
just for kicks, if we multiplied the third option, it would come out to 8 + 4x.

What is the slope between the points (2, 3) and (-1, 12)
Answer:
[tex] \huge \boxed {slope = - 3}[/tex]
Step-by-step explanation:
[tex]m = \frac{rise}{run} [/tex]
The slope is the change of y over the change of x.
[tex]m = \frac{12 - 3}{ - 1 - 2} \\ m = \frac{9}{ - 3} \\ m = - \frac{9}{3} \\ m = - 3[/tex]
Therefore, the slope is -3.

SOLVE FOR X 4 (2x + 3) = 6x + 10 A. -2 B. -1 12 D. 1 OD B А A
Answer:
x= -1
Step-by-step explanation:
4 (2x + 3) = 6x + 10
8x+12=6x+10
8x+12-12=6x+10-12
8x=6x-2
8x-6x=6x-2-6x

1. Carly buys a pair of jeans. The store marks them down 25%. They were originally $59.80 and she has to pay a tax of 8%. What is the price of the jeans after the discount and then tax is applied?
Hey there!
The answer is $48.44
We can solve this by first finding how much the discount is.
0.25 x 59.80
14.95
The amount of the discount is 14.95, so we then take the discount off.
59.80 - 14.95
44.85
Then, we find the amount of tax.
.08 x 44.85
3.588 (round to nearest cent = 3.59)
Then, add the price of the tax onto the price of the jeans.
3.59 + 44.85
48.44
Hope this helps! Good luck!
Footlocker has sale ln any three shirts for $55.50 meanwhile nike is having their own sale ln any five sale shirts for $79.99 which store offers the best deal what is your saving per shirt
Answer:
$55.50 for three shirts
Step-by-step explanation:
The computation is shown below:
For this question we calculate the average for both the options
For the first option, the average is
= $55.50 ÷ 3 shirts
= $18.50 per shirt
For the second option, the average is
= $79.99 ÷ 5 shirts
= $15.998 per shirt
As per the above calculation, the first option is to be best deal as the amount per shirt is high so the same is to be selected

Find the nth term of this quadratic sequence
2, 8, 18, 32, 50, ...
Answer:
nth term = 2n^2
Step-by-step explanation:
The computation of the nth term of the quadratic sequence is as follows;
The given sequence is 2,8,18,32,50
Now
The first term, n = 1 = 2 × 1 × 1 = 2
Second term, n =2 = 2 × 2 × 2 = 8
Third, n =3 = 2 × 3 × 3 = 18
fourth term, n = 4, = 2 × 4 × 4 = 32
fifth term, n =5, = 2 × 5 × 5 = 50
Now finally For nth term, = 2 × n × n = 2n^2
Therefore nth term = 2n^2

Let's take this problem step-by-step:
First step: we note the exponential power is negative⇒ thus we move the whole thing to the denominator
[tex]x^{-\frac{5}{3} } =\frac{1}{x^{\frac{5}{3} } }[/tex]
the Second step, now we need to figure out the fraction that the is an exponent of x⇒ '3' which is on the denominator of the fraction
⇒represents the '3rd' root of x or the cubic root of x
⇒ 5 which is the numerator of the fraction is
⇒represents the 5th power of x or x to the power of 5
Result: [tex]\frac{1}{\sqrt[3]{x^5} }[/tex]
Answer: The second choice or [tex]\frac{1}{\sqrt[3]{x^5} }[/tex]
Hope that helps!

-22 + (-16)
Hhhhhhhhhhhhhhhhhhhhhh
Answer:
-22 + (-16)= -38
Step-by-step explanation:
Answer
-38
Explanation
This is the expression given.
-22+(-16)
Adding a negative number to something is the same thing as subtracting the number.
-22-16
To subtract two negative numbers, you are technically adding the numbers and putting a negative sign.
22+16=38
And put a negative sign in front of that.
So the answer would be -38.

3 adult and 4 child tickets cost £23
1 adult and 5 child tickets cost £15
Work out the cost of an adult ticket and the cost of a child ticket
Answer:
Each child ticket costs £2
Each adult ticket costs £5
Step-by-step explanation:
Let's define:
C = cost of a child ticket
A = cost of an adult ticket.
We know that:
"3 adult and 4 child tickets cost £23"
This can be written as:
3*A + 4*C = £23
"1 adult and 5 child tickets cost £15"
This can be written as:
1*A + 5*C = £15
Then we have the system of equations:
3*A + 4*C = £23
1*A + 5*C = £15
To solve it, we start by isolating one of the variables in one of the equations:
Let's isolate A in the second equation:
A = £15 - 5*C
Now let's replace this in the first equation:
3*( £15 - 5*C) + 4*C = £23
Let's solve this for C
£45 - 15*C + 4*C = £23
£45 - 11*C = £23
£45 - £23 = 11*C
£22 = 11*C
£22/11 = £2 = C
Each child ticket costs £2
And with the equation:
A = £15 - 5*C we can find the price of an adult ticket if we replace the value of C by £2
A = £15 - 5*£2 = £5
Each adult ticket costs £5
Rectangular park has a walking trail on its periphery. If the length of the park is 47 metre and the breadth is 30 metre, then find the distance that a person will cover if he takes 3 complete round(s) of the park. a) 420m b)410m c)462m d)452m
Answer:
c)462m
Step-by-step explanation:
If a person walks round the park, the person would be walking the whole perimeter of the trail
Perimeter = 2 x (length + breadth)
2 x (30m + 47m) = 154m
If he walks three times, the distance covered = 154m x 3 = 462m
