Answer two questions about the following rational multiplication. -3x+21/-2x-4 divided by x^2-16/x-7
What is the product in lowest terms?

What values of x must we exclude from the domains of the expression
A x= -4
B x= -2
C x=4
D x=7

"a" determine whether sage found the correct quotient. show your work

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.
