Answer:

Step-by-step explanation:
As given
Mario is setting up a new tent during a camping trip.
The tent came with 7 feet of rope.
As 1 foot = 12 inches
Now convert 7 feet into inches.
7 feet = 7 × 12 inches
= 84 inches
As given
The instructions were to use 34.5 inches of the rope to tie a tarp on top of the tent.
Than
Rope left after tie a tarp on top of the tent = 84 - 34.5
= 49.5 inches
As given

i.e


Than the equation becomes



x = 6
Answer:
x² - 1 = 8
Step-by-step explanation:
Given the following algebraic expression;
x² - 1
When x = -3
Substituting the value of x, we have;
x² - 1 = (-3)² - 1
x² - 1 = 9 - 1
x² - 1 = 8
Method II.
x² - 1 = (x - 1)(x + 1)
Substituting the value of x, we have;
x² - 1 = (-3 - 1)(-3+ 1)
x² - 1 = -4(-2)
x² - 1 = 8
