Answer:
x = 15
Step-by-step explanation:
2.25x - 10 = 23.75
Add 10 to both sides
2.25x = 33.75
Divide both sides by 2.25
x = 15

<h3>What is an expression?</h3>
An expression is a mathematical equation which shows the relationship existing between two or more numerical quantities or variables.
<u>Given the following expression:</u>
![\sqrt[4]{15^{7} }](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B15%5E%7B7%7D%20%7D)
From the law of indices, we have:
![\sqrt[c]{a^{b} } =a^{\frac{b}{c} } \\\\\sqrt[4]{15^{7} } =15^{\frac{7}{4} }](https://tex.z-dn.net/?f=%5Csqrt%5Bc%5D%7Ba%5E%7Bb%7D%20%7D%20%3Da%5E%7B%5Cfrac%7Bb%7D%7Bc%7D%20%7D%20%5C%5C%5C%5C%5Csqrt%5B4%5D%7B15%5E%7B7%7D%20%7D%20%3D15%5E%7B%5Cfrac%7B7%7D%7B4%7D%20%7D)

Answer:
12 inches
Step-by-step explanation:
The storage bin is in the shape of a rectangular prism.
Its volume is 5400 cubic inches and its base area is 450 square inches.
The volume of a rectangular prism is given as:
V = L * W * H
where L = length
W = width
H = height
The product of the length and width gives the base area of the rectangular prism:
A = L * W
This implies that:
V = A * H
=> 5400 = 450 * H
H = 5400 / 450
H = 12 inches
The height of the bin is 12 inches.
