Okay this is how I would figure this out:
I would take 9 divided by 3 and get 3, so he can tile abut 3 square ft. in 15 minutes.
Then, I would multiply 3 by 4 because there are 4 15 in an hour. I would get 12.
So it takes Jakob 1 hour to tile 12 square feet.
Your answer is: He can tile about 12 square feet per hour.
Hope this helped :)
Hey!
You have to divide the total amount she has by the surface area.
Surface area = 2(wl+hl+hw)
That gives you:
The surface area is 126 ft. Now divide the total amount she has by the surface area.
<em>That means she can cover 9 boxes</em>

Step-by-step explanation:
Answer:
x= - 1
Step-by-step explanation:

Substitute:
|-1 - (-12)| = |-1 + 12| = |11| = 11
<h3>Answer: 11 units.</h3>
