Answer:
-8k + 24
Step-by-step explanation:
Is your expression.
24 cubes, each 8 cubic inches, meaning each 2 inches on a side. So the dimensions must be even to fit cubes exactly. Our box with 9 inches is really only effectively 8 inches because that extra inch doesn't help us fit another cube.
So our total volume:


inches minimum
H = V / B
<span>= 10x3 + 46x2 – 21x – 27 / 2x^2 + 8x - 9
</span>= 5x + 3
Answer: 1,800 ft.³
Step-by-step explanation: To find out how much water is needed to fill the pool, we need to find the volume of the pool. It's also important to understand that the swimming pool is a rectangular prism so we are finding the volume of a rectangular prism.
To find the volume of the pool, we use the formula shown.
<em>Volume = length × width × height </em>
Since the length of the pool is 20 feet, the width is 15 feet, and the depth or height is 6 feet we can plug this information into the formula.
Volume = (20 feet) (15 feet) (6 feet) = 1,800 ft.³
Therefore, it will take 1,800 cubic feet of water to fill the pool.
Answer:
a=3, c=-4, x=8
Step-by-step explanation:
5=4a-7
4a-7=5
4a=5+7
=12
a=12÷4
=3
3-8c=35
-8c=35-3
=32
c=-32÷8
=-4
-1/2x-7=-11
-1/2x=-11+7
=-4
x=4÷1/2
=4/1×2/1
=8
