Multiple Choice

•  $\frac{x+5}{8}$  

•  $\frac{16x+14}{16}$  

•  $\frac{2x+14}{16}$  

•  $\frac{2x+10}{32}$  

Multiple Choice

• $\frac{1+16a^2}{12-3}$

• $\frac{1-16a^2}{12a-3}$

Multiple Choice

You must factor on this question (use desmos to work backwards).

•  $\frac{14k^2-7k^2}{6k^2-5k+1}$  

•  $\frac{7k}{3k-1}$  

Multiple Choice

Factor the right side, then multiply the left by what is missing. THEN factor out a GCF from the numerator after you have added the two together to simplify completely. 

•  $\frac{7y+56}{\left(y+8\right)\left(y+3\right)}$  

•  $\frac{7}{y+3}$  

Multiple Choice

Factor the left side, then multiply the right by what is missing. THEN factor the numerator after you have added the two together to simplify completely. 

•  $\frac{m+5}{m-2}$  

•  $\frac{m^2+7m+10}{\left(m+2\right)\left(m-2\right)}$  

Multiple Choice

Multiply each side by what's missing. THEN factor the numerator after you have added the two together to simplify completely.

• $\frac{b^2-4b-12}{b\left(b+3\right)}$

• $\frac{\left(b-6\right)\left(b+2\right)}{b\left(b+3\right)}$

Multiple Choice

Factor the denominators, then multiply each side by what's missing. THEN factor the numerator after you have added the two together to simplify completely.

• $\frac{r^2-16}{2r\left(r+4\right)}$

• $\frac{r-4}{2r}$
