Answer:
x=5
Step-by-step explanation:
(8x-8)3/2=64
(24x-8)/2=64 -You are distributing the three
12x-4=64 -You divide the whole thing by two
12x=60 -You subtract the four from both sides
x=5 - You divided the twelve from both sides

Answer:
-8i + 51
Step-by-step explanation:
(3+5i)(2-9i)
6+10i-18i-45i²
**i² = -1.
6-8i + -45(-1)
= -8i + 51
x – slower car
3x faster car
D = distance traveled by slower car
D = distance traveled by faster car
D+d = 129
Both cars traveled for 2 hours
D=2x
d=2(3x) = 6x
2x+6x = 129
8x = 129
x=129/8 = 16.125 miles per hour
