Answer:
The total area of the pool section of Keith's backyard is 390 square feet.
Step-by-step explanation:
Since Keith is trying to figure out the area of his pool section in his backyard, and he knows that his pool is 20 feet long and 9 feet wide, and he also knows the sidewalk is 3 feet wide all around the floor, to determine what is the total area of the pool section of Keith's backyard, the following calculation must be performed:
(20 + 3 + 3) x (9 + 3 + 3) = X
26 x 15 = X
390 = X
Therefore, the total area of the pool section of Keith's backyard is 390 square feet.
Step-by-step explanation:
Yes your answer is correct
Just plug in A - 2B + C
5 - 2(4) + 2 = -1
2 - 3(2) + 8 = 4
3 - 2(-1) + 0 = 5
0 - 2(6) + 5 = -5
so
[-1 4]
[5 -7]
