10.
a) x- is the time after which the total cost is the same.
24 + 99x - is the cost in the dealership
45 + 89x is the cost at the local mechanic
24 +99x = 45 + 89x
99x - 89x = 45 - 24
10x = 21
x= 2.1 (hours)
b) 24 +99x < 45 + 89x
x< 2.1
The repairs cost less in dealership when work takes less than 2.1, and the dealership is better, because the cost of parts is less in the dealership.
The answer is 30,000
20,100 / 0.67 = 30,000

Answer:
x(x+5)[(x+5)² +3(x-1)]
Step-by-step explanation:
(x²+5x)(x²+13x+22)
Expand
(x²+5x) (x²+13x+22) by multiplying each term in the first expression by each term in the second expression.
x²x²+x²(13x)+x²⋅22+5x⋅x²+5x(13x)+5x⋅22
Simplify terms.
x⁴+18x³+87x²+110x
