Process
To solve this problem just multiply the numerator by the numerator and the denominator by the denominator. If is possible, simplify the result.

Multiply the numerators (3x)(x) = 3x²
Multiply the denominators (x + 2)(x - 1) = x² + x - 2
- Join the results 
Question 3: 3/8 you just need to multiply across in order to get your answer
Answer:
5
Step-by-step explanation:
405=9x9xj
rearrange
j=5
F(x)=2x³+x-3
f(-2)=2(-2)³+(-2)-3
f(-2)=2(-8)-2-3
f(-2)=-16-2-3
f(-2)=-18-3
f(-2)=-21. As a result,C is your final answer. Hope it help!
