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

Answer:

Option C. X=A/4

Step-by-step 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

$X=\frac{A}{4}$
