Simplify the expressions.

a. 7 + 10x – 7 + 7x

b. 6 + 8b – 8b2 + 3b – 6 – 10b2

A. 17x  B. -18b2+11b

Step-by-step explanation:

10x + 7x = 17x

7-7=0

answer is 17x

-8b2-10b2= -18b2

8b+3b=11b

6-6=0

answer is -18b2+11b

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
