The answer is C. If the original equation is 10+20 for one swing, you multiply that by 3 to get the cost of three swings
Answer:
x=-4
x=4
Step-by-step explanation:
We can factor x^2 -16 = 0 by recognizing that it is a difference of squares. That means we can factor the equation to (x-4)(x+4) = 0. By using the Zero Product Property we know that either (x-4) or (x+4) is equal to 0. That means that x either equals -4 or 4.
To find the answer, multiply 22 1/2 by 3.
22 1/2 x 3 = 67 1/2
This can round up to 68
The answer is C. 68 mph
