Step-by-step explanation:
After 19 months, the cost will be same for both memberships.
Step-by-step explanation:
Given,
Sign up fee at Power Plus = $22.00
Per month fee = $34.14
Let,
x be the number of months.
P(x) = 34.14x + 22
Sign up fee at Heavy Hulk = $34.50
As they have cut the cost into half.
Sign up fee = 
Per month fee = $34.39
H(x) = 34.39 + 17.25
For same cost ;
P(x) = H(x)

Dividing both sides by 0.25

After 19 months, the cost will be same for both memberships.

Answer:
- perimeter: 36 +16√5 ft ≈ 71.777 ft
- area: 288 ft²
Step-by-step explanation:
<u>Perimeter</u>
The perimeter is the total length of all the sides. The length of the horizontal sides is 8 ft + 10 ft = 18 ft. The length of the slant sides can be found using the Pythagorean theorem. For side length s, we have ...
s^2 = 8^2 + 16^2
s^2 = 64 +256 = 320
s = √320 = 8√5
Then the perimeter is ...
P = 2(8√5 + 18) = 36 +16√5 ≈ 71.777 . . . feet
__
<u>Area</u>
The area is given by the formula ...
A = bh
where b is the base and h is the height.
A = (18 ft)(16 ft) = 288 ft²
