The length of a rectangular soccer field is 40 feet more than twice the width of the field. complete an equation for the area of the field, where w is the width of the field. a = +

Step-by-step explanation:

let the width be w

therefore, length=2w+40

area of a rectangle=l*b

l=2w+40 and width=w

A=(2w+40)*w

answer: i believe c. is the answer sorry if i am wrong

step-by-step explanation:

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).
