What are the solutions of the equation x^2+15=79?

<h3>Answers:  x = 8 and x = -8</h3>

========================================================

Work Shown:

x^2 + 15 = 79

x^2 = 79-15

x^2 = 64

x = sqrt(64) or x = -sqrt(64)

x = 8 or x = -8

As the steps above show, we first subtract 15 from both sides. Then we apply the square root to get the two results. Don't forget about the plus minus.

A rectangular pool is 7 feet wide. It is 3 times as long as it is wide.
aliina [53]

Answer:

7x21

Step-by-step explanation:

First, we need to find the length of the pool. Since it is three times as long as it is wide, it is 21 feet long (7 x 3 = 21). That way we can tell that it is 7x21, with a perimeter of 56 feet, and an area of 147 feet squared.

Four subtracted from eight is equal to two squared
Scilla [17]
Yes. This is true because 4 subtracted from 8 is 8-4=4. The value you get from subtracting 4 from 8 equals the same value you would get if you were to take the value of 2 and square it. Both equal 4.

Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative <u>YOU MUST FLIP THE INEQUALITY SIGN.</u>
