Awindow in the shape of a rectangle as shown below has a width of x+5 and a length of x^2- 3x+7 express the area of the rectangle as a single polynomial in simplest form

Step-by-step explanation:

since a=lw, the area is (x^2-3x+7)(x+4)

1. distribute parentheses

2. apply +(-a)=-a rule

3. Simplify

    Steps to simplify:

4. Add like terms

5. Add like terms

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

step-by-step explanation:

a
