First find the area of each wall. This is length*width which would be 12*8.5=102. There are four walls in the room because it’s a square so that would be 102*4=408. So the total area you need to paint is 408ft one gallon will cover 75ft so 408/75=5.44 gallons of paint.
<h3>Answer:</h3>
Mean: 17.2
Median: 18
Mode: 18
<h3>Solution:</h3>
Mean: The sum of all observation divided by several observation
- 20+18+13+17+18=86
- 86÷5=
- 17.2
Median:it is the middlemost observation of data arraged in increasing or decreasing order of values
- (13,17,18,18,20)
- (17,18,18)
- (18)
Mode:it is the value that occurs frequently in a set of data
Hope it helps
Answer:
D
Step-by-step explanation:
So we have the equation:

And we want to solve for x.
We can solve it by completing the square.
First, subtract 58 from both sides:

Divide the b term by 2 and square it:

So, add 9 to both sides:

On the left, the perfect square trinomial pattern. Add on the right. So:

Take the square root of both sides:

The square root of -49 is 7i:

Add 3 to both sides:

So, our answer is D.
And we're done!
40 to the second power is 1600!
