The equation p = 2{e + w} can be used to find the perimeter p of a rectangle with length e and width w. solve the equation for w to produce the formula for finding the width of a rectangle given its perimeter and length

Step-by-step explanation:

Divide by 2, then subtract the length.

_____

A script L is sometimes used to avoid confusion with I (eye) or 1 (one). It can look like an "e".

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
