Answer:
<h3> Perimeter = 3√5 + 6 + √73 + √58 + 5√2</h3>
Step-by-step explanation:

She had to sell 20 T-shirts
The profit plus the rent fee is $40. Then divide it by the T-shirt price $2. Which equals $20.
It is called associated property.
The ( ) are moved around, but the answer will be the same.
Well c is the cost to rent the locker for 1 hour, the 1.5 is the rental time, so multiplied together, you get the 9 which is the total cost to rent the locker for the number of hours you had it for.
for example: if you were to rent the locker for 1 hour (t = 1) the equation would look like c(1) = total cost.
*hopefully this is making sense*
another example: if you wanted to find out what the base rate is to rent the locker for 1 hour, you would just solve for c in the given equation
c(1.5) = 9 c = 9/1.5 c = 6
