In a set of picture frames, frame 1 has a length that is 5 inches longer than its width, w, and frame 2 has the same length as frame 1, but is 2 inches wider than frame 1. The area of frame 2 is 28 square inches more than the area of frame 1.

Part 1

Which equation will help find the area of frame 2?
A.
w(w + 5) + (w + 2)(w + 5) = 28
B.
w(w + 5) + 28 = (w + 2)(w + 5)
C.
(2w + 5)(2w + 7) = 28
D.
(2w + 5)(2w + 7) + 28 = 0

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
