Lupe’s Construction is building a rectangular house that is 16 feet longer than it is wide. They will be putting a 3-foot wide s
mr Goodwill [35]

Answer:

The length of the four pieces of protective strip is 96 feet

Step-by-step explanation:

Let the w be the width of the rectangular house and L is length. Since L = w + 16, its perimeter P = 2(w + L)

= 2(w + w + 16)

= 2(2w + 16)

Since the perimeter of the house P = 136 feet,

136 = 2(2w + 16)

dividing through by 2, we have

136/2 = (2w + 16)

68 = (2w + 16)

collecting like terms, we have

68 - 16 = 2w

52 = 2w

dividing through by 2, we have

w = 52/2

w = 26 feet.

Now, since the side walk is 3 foot wide all around, the width of the house plus sidewalk = w + 3 and the length of the house plus sidewalk = L + 3 = w + 16 + 3 = w + 19.

So, the perimeter of the house plus sidewalk which is the perimeter of the four pieces of protective strip is P' = 2(w + 3 + w + 19)

= 2(w + 22)

= 2(26 + 22)

= 2(48)

= 96 feet

So, the length of the four pieces of protective strip is 96 feet.

Answer:

6 photos more if you use the fast printer

30 photos

Step-by-step explanation:

To figure out the answer, it will be much easier to figure out how many pages each printer can print in 1 minute. For the office printer, we need to divide both numbers by 12.5. This means that the office printer can print 2 pages per minute.

Do the same thing for the home printer. We need to divide both numbers by 6. This means that the home printer can print 2.5 pages per minute.

The home printer is indeed faster.

Now, we need to figure out how many more pages can the home printer print in 12 minutes. In 12 minutes, the office printer can print 24 pages. In 12 minutes, the home printer can print 30 pages. The difference in the number of pages between the faster printer and the slower one within 12 minutes is 6 pages.
