It's multily
f(x) time g(x) is basically what they wnat
so
(x^2+8x+15) times (5/(x^2-9))
hold a sec, first factor each
(x+3)(x+5) times 5/((x-3)(x+3))
we get
((x+3)(x+5)(5))/((x-3)(x+3))
(x+30 cancels out
((x+5)(5))/(x-3)
(5x+25)/(x-3)
3rd option
Answer
Step-by-step explanation:
Answer:
First make mixed
4 x 5 = 20
20 + 2 = 22
22/5 = 4 2/5
1 x 5 = 5
5 + 1 = 6
6/5= 1 1/5
Multiply the reciprocal. The reciprocal is the fraction flipped over like 1/2 becomes 2/1
22/5 / 6/5 = 22/5 x 5/6
Multiply
22 x 5 = 110
5 x 6 = 30
110/30
Simplify
110/10=11
30/10=3
Answer is
11/3 = 3 2/3
