We assume that we need to simplify the expression in two different ways.
Answer:
One way: Raise both, the numerator and denominator, to the third power, and then simplify the expression.
Second way: Simplify the terms inside parentheses, and then raise the result to the third power.
The result of both ways is the same:
Step-by-step explanation:
<em>One way</em>
Raise both, the numerator and denominator, to the third power, and then simplify the expression:
This is the first simplification.
<em>Second way</em>
Simplify the terms inside parentheses, and then raise the result to the third power.

D.) equilateral triangles are acute.
- In an equilateral triangle, the 3 angles are always 60 degrees.
Answer: A 40 feet
Explanation:
If a building is 380 feet tall and the elevator has to descend 420 feet to get to the underground parking garage. So 420 - 380 to remove the height of the building from the equation. This would give us 40 feet underground left until the elevator reaches its desired destination.
In questions 27 and 28, the unknown is called x.
Answer:
49
Step-by-step explanation:
Solve. Note that the power sign is 2. When a number has a power, you are essentially multiply the same number (the power sign's number) of times over.
In this case, your power sign is 2, so you will multiply 7 twice:
7 x 7 = 49
49 is your answer.
