Answer:
x equals -1 and it also equals -13. They are both considered the roots.
Step-by-step
- (x+6)^2= 49 to get rid of the exponent square root each side of the equation.
- (x+6)= √49 Find square root of 49.
- (x+6)= ±7 It could be positive 7 or -7 because both of them squared equal 49. Now solve for each possible equation, (x+6)= 7 and (x+6)=-7.
- (x+6)=7 subtract 6 from each side.
- x= 1
- (x+6)=-7 Subtract 6 from each side.
- x=-13
- So the answers are -13 and 1.

Answer:
$102.50
Step-by-step explanation:
The formula here would be x=35+15y, y being the number of hours he was there.
So 35+15(4.5)=102.5, or $102.50.
