Answer:
5 hours
Step-by-step explanation:
The volume of the pool is ...
V = LWH
V = (10 ft)(8 ft)(5 ft) = 400 ft^3
At the given fill rate, the time it will take is ...
(400 ft^3)/(80 ft^3/h) = 5 h
It will take 5 hours for the pump to fill the pool.
Square both sides
9(x + 2) = x + 4
Expand
9x + 18 = x + 4
Subtract x from both sides
9x + 18 - x = 4
Simplify 9x + 18 - x to 8x + 18
8x + 18 = 4
Subtract 18 from both sides
8x = 4 - 18
Simplify 4 - 18 to -14
8x = -14
Divide both sides by 8
x = -14/8
Simplify 14/8 to 7/4
<u>C. x = -7/4</u>

Answer: B and C
Step-by-step explanation:
Let's start off with some definitions.
Supplementary Angles: Two angles that add up to 180°.
Right Angle: One angle equal to 90°. Also identified with a square on the angle.
Complementary Angles: Two angles that add up to 90°.
Straight Angle: A straight line, which equals to 180°.
Right off the bad, we can knock off A and D because there is no proof of those being seen.
The angle <EFH is a right angle because it is equal to 90°. If you pay close attention, the angles <EFG and <GFH both add up to 90°, making them complementary angles.
Therefore, the correct answers are <u>B and C.</u>
I hope this helps! Pls mark brainliest!! :)
