The width of a rectangle is 8 inches shorter than its length. The perimeter of the rectangle is 18 inches. What are the length and width? Which equation models this problem? A. 8 • l = 18 – 8 B. 2l + 2(l – 8) = 18 C. l + (8 + 2l) = 18 D. l(l – 8) = 18

B

Step-by-step explanation:

Let length be l

Width, w=l-8

Perimeter = 2(l+w) = 2l+2w

2l+2(l-8)=18

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
