If a rectangular prism has a volume of 470.40 cm³, and the length and width is equal to 6.4 and 9.8, we will find the height by using some inverse operations. We will use the variable h to represent height

Length x Width x Height = Volume
6.4 cm • 9.8 cm `• h = 470.40

470.40 ÷ (9.8 x 6.4)
 = 470.40 ÷ 62.72
 = 7.5

Check Answer:
Length x Width x Height = Volume
6.4 cm • 9.8 cm `• 7.5 = 470.40

Answer: 7.5 cm

Which of the following can be added without altering any of the fractions?

Murrr4er [49]

<h3>Answer: Choice A</h3>

Why? Because the denominators are both the same at 2x+8. We can only add or subtract fractions when the denominators are the same. The general rule for adding fractions is

$\frac{A}{C}+\frac{B}{C} = \frac{A+B}{C}$

We have numerators A and B added together over a common denominator C. If we didn't have a common denominator, then we'd have to do a bit of algebraic manipulation to get both fractions to a common denominator. It doesn't have to be the lowest common denominator (LCD), though it's often more efficient that way.
