An open top box with a square base is to have a volume of 350 cubic meters. The material for the bottom of the box costs $2 per square meter and the material for the sides costs $6 per square meter. Write an expression that represents the cost of constructing the box in term of x, the side length of the base.

Step-by-step explanation:

Given

Volume of box

Suppose base square has a length

and vertical walls has length of

volume

Cost of bottom material per square meter

Cost of side material per square meter

Total cost

yes

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
