Your surface area is: S=x^2+4xh=84 square inches and h=2 inches; so you get:
x^2+(4×2)x=84
x^2+8x-84=0 qhich is a quadratic equation. Using the quadratic formula you get two results for x:
x1=-14 and x2=6
choose the second (positive)

Answer:

D. Graph A

Step-by-step explanation:

First, notice the function can be factored easily:

$y=x^2+10x+16 =(x+8)(x+2)$

So we can see that the function hits the y-axis at 2 points:

(-8,0) and (-2,0).

Which of the graphs in the picture show a parabola that hits the y-axis at those points? Graph A is the only option.

So the answer is D. Graph A

A rectangular room has an area of 131 1/4 square feet. the length is 12 1/2feet what is rhe width

Tamiku [17]

The formula for the area of a rectangle is A=L x W

Plug in the numbers to the formula then solve:
131 1/4 = 12 1/2 x W

first divide 131 1/4 by 12 1/2 to get 10 1/2

so, the width of the rectangular room is 10 1/2 feet
