L = H - 24
L = low temperature.
H = High Temperature = 92 degrees
L = 92 - 24
L = 68

See below:
Step-by-step explanation:
We can first setup an equation by doing the following:

Whole proccess above!
If you would like an explanation, please let me know so.
Its basically algebra and it's mainly on how you interpret it!
Have a nice day!
We are told that f(x) = x + 2. We want to find
.
Squaring f(x) on one side means we square x + 2 on the other.
So,
f(x) = x + 2
(f(x))² = (x + 2)²
= (x + 2)(x + 2)
We can use FOIL to square x + 2. The first terms multiply to x², the outside terms to 2x, the inside terms to 2x and the last terms to 4.
= x² + 2x + 2x + 4
= x² + 4x + 4
So [f(x)]² = x² + 4x + 4
The perimeter of the triangle with those given lengths is
