It helps to draw a picture so you can visualize it better.
For the rug, since the area = 144, what two numbers multiplied give you 144? You might already know that 144 is a perfect square, so 12 x 12 = 144. 12 is the length of each side of the rug.
√144 = 12
12 + 3 = 15. (Add 3 because the rug only covers a portion of the floor. The entire floor = the length of the rug + the part that isn't covered)
15 x 15 = 225 ft squared (Multiply both sides of the floor to get the area.)
225 ft squared - 144 ft squared = 81 ft squared <-- your answer
Answer:
- 4
Step-by-step explanation:
The average rate of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 2, 2 ]
f(b) = f(2) = 9 ← from table value of f(x) for x = 2
f(a) = f(- 2) = 25 ← from table value of f(x) for x = - 2, thus
average rate of change = = = - 4
