Answer:

350 people can fit into 42 rooms

Step-by-step explanation:

So we can write it as a relation fraction equation:

\frac{50}{6}=\frac{x}{42}

Where:

x represents the people can fit in 42 rooms

x=\frac{50*42}{6}

x=350

Therefore, <u>350 people can fit into 42 rooms.</u>

I hope it helps you!

The perimeter of a rectangle is represented by
MissTica

The perimeter of a rectangle is represented by 4x^2 + 5x − 2. The perimeter of a smaller rectangle is represented by x^2 + 3x + 5. Which polynomial expression BEST represents how much larger the first rectangle is than the smaller rectangle?

A) 3x^2 + 2x − 7

B) 3x^2 + 2x − 3

C) 3x^2 + 8x + 3

D) 5x^2 + 8x − 7

<h3><u>Answer:</u></h3>

Option A

The polynomial expression best represents how much larger the first rectangle is than the smaller rectangle is 3 x^{2}+2 x-7

<h3><u>Solution:</u></h3>

Perimeter of a rectangle is represented by 4x^2 + 5x − 2

Perimeter of a smaller rectangle is represented by x^2 + 3x + 5

To Find : Polynomial expression that represents how much larger the first rectangle is than the smaller rectangle.

Which means we have to find difference between perimeter of both rectangles

Subtract the equation of perimeter of  smaller rectangle from equation of  perimeter of a larger rectangle

Difference = perimeter of a larger rectangle - perimeter of  smaller rectangle

\text {Difference }=\left(4 x^{2}+5 x-2\right)-\left(x^{2}+3 x+5\right)

On removing the brackets we get,

\begin{array}{l}{\text { Difference }=4 x^{2}+5 x-2-x^{2}-3 x-5} \\\\ {\text { Difference }=3 x^{2}+2 x-7}\end{array}

Thus option A is correct
