Multiply everything in the second parenthesis by x.

-3x^3 + 3x^2 + x

Multiply everything in the second parenthesis by 2.

-6x^2 + 6x + 2

Combine these two equations together.

-3x^3 + 3x^2 + x - 6x^2 + 6x + 2

Combine like terms.

-3x^3 - 3x^2 + 7x + 2

Hope this helps!

The perimeter of the hall is the sum of its side lengths.

The perimeter of the museum exhibit hall is 240 feet

<h3>How to determine the perimeter</h3>

From the question, we understand that the shape of the museum exhibit hall is a regular octagon

The perimeter of a regular octagon is:

p = 8l

Where l represents the side length of the octagon

So, we have:

p = 8 * 30 feet

Evaluate the product

p = 240 feet

Hence, the perimeter of the exhibit hall is 240 feet

erma4kov [3.2K]

The journey is broken down into five segment

Shop - first delivery = $12 \frac{1}{3}$ miles
First delivery - second delivery = $8 \frac{3}{4}$
Second delivery - third delivery = $17 \frac{2}{8}$
Third delivery - fourth delivery = $23 \frac{2}{3}$
Fourth delivery - shop = $10 \frac{5}{10}$

The average distance for each segment are:
$[12 \frac{1}{3}+8 \frac{3}{4}+17 \frac{2}{8}+23 \frac{2}{3}+10 \frac{5}{10} ]$ ÷ $5$

$\frac{145}{2}$ ÷5 = $\frac{29}{2}=14 \frac{1}{2}$
