Answer:
16 times
Step-by-step explanation:
Membership cost:
C = 135 + 2x
Non-members:
C = 11x
____
135 + 2x = 11x
135 = 9x
x = 15
The cost would be the same after renting 15 times, so after 16 times the cost would be cheaper for a member.
Answer:
The zeroes would be -3 and a double root at 5.
Step-by-step explanation:
We can find this by first expanding the function.
c(x) = (x + 3)(x - 5)^2
c(x) = (x + 3)(x - 5)(x - 5)
Then we can solve for the zeroes by setting each parenthesis equal to 0 and solving.
x + 3 = 0
x = -3
x - 5 = 0
x = 5
x - 5 = 0
x = 5

Simplify the equation.
First, distribute the 2 in the left side of the equation.
Resulting in: 2x-6 = (x-1) + 7
Second, remove the parentheses form the right side of the equation (there is nothing to distribute there).
Resulting in: x - 1 + 7
Now simplify the right side of the equation by subtracting the 1 from the 7.
Resulting in: x + 6
Our goal is to isolate the x to the left side, and the numerals to the right side.
With that in mind, add the 6 (from the right side) to both sides. This cancels out the 6 on the right side.
Resulting in: 2x = 12
Lastly, in order to fully isolate the variable (x), we divide both sides by 2.
Resulting in: x = 6
Hope this helps.
