The power of two is any number squared.
Example~ 3*3, 5*5, 8*8
77 - (-145) = 77 + 145 = 222

Answer:
x = 6 y = -9 (I took a complicated route so if my explanation doesn't make sense It's fine)
Step-by-step explanation:
DAY = FUN
F = (7x+2y) = 24
If DAY = FUN then D = F making (7x + 2y) = 24
This means A = U so you have to find U with 24+126=150
A triangle is 180 degrees so you would do 180-150=30
U = 30
This also makes (8x+2y) = 30
8x + 2y = 30
-8x -8x
2y = 30 - 8x
Divide everything by 2
y = 15 - 4x
Doing this you can take 7x + 2y = 24 and plug in 7x + 2(15 - 4x) = 24
Multiply it 7x + 30 - 8x = 24
Add like terms -x + 30 = 24
Subtract 30 -x = -6
Divide by -1 x = 6
Now take one of the equations and plug it in 7(6) + 2y = 24
Multiply 42 + 2y = 24
Subtract 2y = -18
Divide by 2 y = -9
The height of the pole is 12.5 feet.
<h3>What is Unitary method?</h3>
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Cindy's shadow is 5 feet.
length of the shadow of the pole at the same time, she finds it to be 12.5 feet.
So,
12.5/5=x/5,
62.5=5x
x= 12.5 feet.
Hence, the height of the pole is 12.5 feet.
