The length of a rectangle is 3 meters less than twice the width. the perimeter is 18 meters. find the width

Length (L): 2w - 3

width (w): w

Perimeter (P) = 2L + 2w

                18 = 2(2w -3) + 2(w)

                18 = 4w - 6 + 2w

                18 = 6w - 6

                24 = 6w

                  4 = w

Length (L): 2w - 3   = 2(4) - 3   = 8 - 3   = 5

width = 4 meters, length = 5 meters

they are simplified

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
