The length of a rectangle is 2 cm longer than its width. if the perimeter of the rectangle is 40 cm , find its area.

rusak2 [61]

width = w

length = w +2

perimeter = 2L + 2w

40 = 2(w+2) + 2w

40 = 2w+4 +2w

40 = 4w+4

36=4w

w=36/4 = 9

with = 9

length = 9+2 = 11

area = l x w = 9*11 = 99 square cm

What is the x intercept of the function x^3-5x^2-8x+48

Zinaida [17]

Answer:

(x+3)(x-4)^2

Step-by-step explanation:

= (x+3)(x^3-5x^2-8x+48)/(x+3)

= x (x^3-5x^2-8x+48)/(x+3)

= x^2-8x+16

= (x+3)(x-4)(x-4)

= (x+3)(x-4)^2
