Question

A post it note has an area of A square inches. The width of the post it note is 4 inches.which equation represents X the length of the post it note in inches A X=4/A. B. X=A+2(4) C. X=A/4. D. X=A-2(4)

Answer 1

Option C. X=A/4

Explanation:

we know that

The area of the rectangular post it note is equal to

`A=LW`

where

L is the length

W is the width

In this problem we have

`W=4\ in\\L=X\ in`

substitute

`A=4X`

solve for x

That means ----> isolate the variable x

Divide by 4 both sides

`X=(A)/(4)`
