Step-by-step explanation:

We now that Brian wants the piece of fabric between 49 and 53 inches, this range is expressed like this

Now, to choose the right answer, we have to transform the from feet to inches and see which one falls into this interval.

We know that 1 ft equals 12 in. If we have , how much inches would be?

As you can see, the choice A is not the right answer because is more than 53.

We do the same process. We know that,   how much inches would be?

Choice B is not the answer neither, because it's outside the interval.

how much inches would be?

As you can observe, choice C is in the interval. Therefore, the right answer is choice C, because 51 inches is between 49 and 53 inches.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
