Answer:
f(-2) = 90
Step-by-step explanation:
Plugging in the value of f(x) into the equation:
f(-2) = 5(-2)3^(-2)
f(-2) = 5(-2)(-9) - evaluate the power first
f(-2) = 90 - multiply from left to right to obtain answer
Answer:
30 is the perimeter i think 2 x 5 = 10 + 2 x 4.5 = 10 x 2 = 20 so 20 + 10 = 30
I think the area is 45, 5 x 4.5 = 22.5 and 2 x 22.5 = 45

In step 3: it should be m + n + o = o + p
Therefore the answer is C.
Answer:
21
Step-by-step explanation:
In the chart, the left side increases by one, and the right side increases by 3. So the left side multiplied by 3 will give you the right side. 7 x 3 = 21, so he will need 21 cups of water.
