They are not. The easiest way to tell this is by multiplying the last number of each parenthesis together. This should always result in the last number in the equation. However, -8*5 does not equal -30, so these are not the true factors.

You verify your answer by using the F.O.I.L. method. First Outside Inside Last. This shows that (x+5) & (x-8) is not the correct factors for 2x-2x-30 or x2-2x-30. Either way, the factors are not right for either of those equations. Hope my answer helps you

Answer:

D. 116

Step-by-step explanation:

V=(\frac{1}{3})\pi r^{2}h

V = (1/3)π(4)²(6.9)

V = 36.8π

V ≈ 115.55

<em>Note: You will NEVER use slant height to calculate the area, only to calculate the normal height if unknown. In this problem, we did not use it at all so try not to get confused!</em>

How would the number of times edgardo uses a container to fill the 10 gallon cooler change if he uses a one cup container? Expla
olya-2409 [2.1K]

Answer:

Edgardo would use the container <u>160 times</u> to fill.

Step-by-step explanation:

Given:

Edgardo uses a container to fill the 10 gallon cooler.

If he uses a one cup container.

Now, to find the times it would take to fill the 10 gallon container.

As, the capacity of container = 1 cup.

And, the capacity of cooler = 10 gallon.

So, we use conversion factor to find the times the container to fill the cooler:

1 gallon = 16 cups.

10 gallon = 10\times 16\ cups.

10 gallon = 160 cups.

<u><em>Thus, to fill the 10 gallon cooler 160 cups of container needed.</em></u>

<u><em>And, the container is of 1 cup.</em></u>

So, to get the times he would use the container we divide 160 by 1:

160\div 1=160.

<u><em>Hence, 160 times Edgardo would use the 1 cup container to fill the 10 gallon cooler.</em></u>

Therefore, Edgardo would use the container 160 times to fill.
