Answer:

Step-by-step explanation:
Four sets of three Squared
To start, you will need to get the set(base number) and get the exponent 3 and put it on the top.

Hope this helps!
Line I is a perpendicular bisector because it bisects another line at right angles via the point of intersection or midpoint. See the Perpendicular Bisector Theorem below.
<h3>What is the perpendicular bisector theorem?</h3>
According to the theorem of perpendicular bisector, any locus on the perpendicular bisector is equidistant from the terminal points of the line segment on which it is created.
Thus, Line I is a perpendicular bisector because it bisects another line at right angles via the point of intersection or midpoint. See the attached image.

The difference in the pay rate of Phoebe in 5 years will be $11850
<h3>How to calculate the pay? </h3>
Your information is incomplete. Therefore, an overview will be given. Let's assume that the pay rate is $20000. When there is a 5% increase, the new pay rate will be:
= $20000 + (5% × $20000)
= $20000 + $1000
= $21000
When there is $0.75 increase per hour, the new pay rate on 5 years will be:
= (0.75 × 43800)
= $32850
The difference will be:
= $32850 - $21000
= $11850

First you add 3 twice to both sides of the swimming pool
12 + 6 = 18
15 + 6 = 21
The perimeter is the sum of all sides therefore
18 + 18 + 21 + 21 = 78
The answer is A
