evablogger [386]
No.

If the Den is 547.35 Square feet, and one side length is 26.7, you divide the Area by one side length to get the other. 547.35/26.7= 20.5

20.5 is less than <span>23.5. Therefore the rug will not fit.</span>

defon

Answer:

c) -20x^2+14x+12

all real numbers

Step-by-step explanation:

So (fg)(x)=f(x)g(x)=(-4x-2)(5x-6).

Need find the expression in standard form we need to use foil:

First:  (-4x)(5x)=-20x^2

Outer: (-4x)(-6)=24x

Inner:  (-2)(5x)=-10x

Last:  (-2)(-6)=12

--------------------------Add like terms:

-20x^2+14x+12

Polynomials have domain all real numbers.

There are no restrictions on what x can be.  For every number you plug in, you will get a number back.
