Answer:
See below.
Step-by-step explanation:
So we know that a gym membership costs $25 plus $14 each month.
In other words, the one-time cost is $25 and there will be a cost of $14 each month.
We can write this as:

Where f(x) equals the total cost given the number of months x.
For 6 months, the total cost will be:

When dividing these, the powers are subtracted form each other.
We could split up the fraction into r's, s's, and t's.
r^-3 / r^2 = r^-5 [think of it as -3 -2]
s^5 / s = s^4
t^2 / t^-2 = t^4 [2 - - 2 = 4]
A negative power places it on the bottom of the fraction and the minus sign is removed from the power.
So the answer is A: (s^4)(t^4)/r^5
Answer:
P = 2x + 2y + 8
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2(l + w) ← l is length and w is width , then
P = 2(x + 5 + y - 1) ← distribute parenthesis
= 2x + 10 + 2y - 2 ← collect like terms
= 2x + 2y + 8
