Nikitich [7]

Correct option is  B)

Cross-multiplication is helpful in Solving proportions.

<h3>What is Solving Proportions?</h3>

Solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying and solving the resulting equation.

<h3>What are the 2 methods for solving proportions?</h3>

Method I: Draw a double-sided number line, label the parts, set up a proportion and solve.

Method II: Using any method, calculate unit rate and then calculate how many pounds you can get for $30. Method III: Graph a point to represent the original ratio.

<h3>What is the rule for solving proportions?</h3>

The product of the means is equal to the product of the extremes.

A rectangular prism has a volume of 16y^4+16^y^3+48y^2 cubic units. Which could be the base area and height of the prism?
Liula [17]
\bf \textit{volume of a rectangular prism}\\\\&#10;V=Bh~~&#10;\begin{cases}&#10;B=area~of\\&#10;\qquad its~base\\&#10;h=height\\&#10;-----------\\&#10;V=16y^4+16y^3+48y^2&#10;\end{cases}&#10;\\\\\\&#10;16y^4+16y^3+48y^2=Bh\implies 16y^2(y^2+y+3)=Bh

so since its just two factors, you can pick either for the "B" or "h", or one can say that the trinomial is the "B", because it can be factored into a couple more binomials, either way will work.
