x^2 in the function that you typed is x * x ( x multiplied by x). It represents a second degree because there are only 2 "x"s multiplied together. If there were 3 "x"s multiplied together, we would have x^3. Since the highest exponent in this function is 2 (in x^2), we call this function a 2nd degree polynomial.

A 12 foot by 8 foot rug covers the hardwood floor of a room. The rug leaves a uniform

trapecia [35]

Answer: 2(12 × 8)

Step-by-step explanation:

The area of the rug will be gotten by multiplying the length by its width. This will be:

= 12 foot × 8 foot

= 96feet²

Since the area of the room is twice the area of the rug, the equation you will use to solve for x will be:

= 2(12 × 8)

= 2(96)

= 192feet²

Answer:

$V=90$

Step-by-step explanation:

<u>Step 1: Find the volume of the cone</u>

<u /> $V = \frac{\pi *r^{2}*h}{3}$

<u>Plug in the values</u>

<u /> $V = \frac{\pi *3^{2}*10}{3}$

<u>Simplify and Solve</u>

<u /> $V = \frac{\pi *9*10}{3}$

$V = \frac{90\pi }{3}$

$V = \frac{90*3 }{3}$

$V=90$

Answer: $V=90$

Yolanda, Hong, and Ahmad served a total of 70 orders Monday at the school cafeteria. Yolanda served 6 fewer orders than Ahmad. H

irina [24]

Answer:Yolanda served 13 orders.

Ahmad served 19 orders.

Hong served 38 orders.

Step-by-step explanation:

Let x represent the number of orders that Ahmad served.

Yolanda served 6 fewer orders than Ahmad. This means that the number of orders that Yolanda served is x - 6

Hong served 2 times as

many orders as Ahmad. This means that the number of orders that Hong served is 2x

Yolanda, Hong, and Ahmad served a total of 70 orders Monday at the school cafeteria. This means that

x - 6 + x + 2x = 70

4x - 6 = 70

4x = 70 + 6 = 76

x = 76/4 = 19

Hong served 2 × 19 = 38

Yolanda served 19 - 6 = 13
