Bojangles has a rectangular shaped roof with a width of 6x2 feet and a length 12x3. what is the area of the roof?

432 square feet

or 72*x^5 square feet

Step-by-step explanation:

Let's remember that the formula of the area of a rectangle is A = L*W, where L is the length and W the width.

In this case, L = 12*3 feet and W = 6*2 feet.

With this information,

A = 12*3 feet * 6*2 feet = 432 square feet

A = 432 square feet

But what you wrote can also be interpreted as L = 12*x^3 feet and W = 6*x^2 feet.

In that case, A = 12*x^3 feet * 6*x^2 feet = 72*x^5 square feet

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
