3x -1
2x 10
(3x-1)(2x+10) = 2(3x-1)(x+5)
<span>(y^5)^2 = y^10
This is power of a power property</span>
Divide the $90 by 5 hours,
giving you $18 per hour.
a. $18x8=$144
b. 6 hours
I agree with the person above
<span>If M is the midpoint of CD, CM = 2x+3 and MD = 3x-6, then:
MD = CM
3x - 6 = </span>2x + 3
3x - 2x = 3 + 6
x = 9
CM = 2x+3 = 2*9+3 18+3 = 21
MD = CM = 21
CD = CM + MD = 21 + 21 = 42
