Please I need this Eva reads 25 pages per hour. Which expression represents the number of pages she reads in h hours?

25h

Step-by-step explanation:

Pages read in 1 hour = 25

So pages read in h hours = 25 × h = 25h

123 square feet

Step-by-step explanation: The question is a little odd, but I can break it down easily. It wants us to find the area of a three foot border around his room.

First, the whole area of his room is 20 x 24 = 480

Next, we have to make the measurements 3 feet smaller on each wall, so 17 x 21 = 357

Finally, to find the area of the border, we simply do 480 - 357 = 123

He needs to buy 123 square feet of carpeting

Hope this helps!
