Answer:
- 8
Step-by-step explanation:
To evaluate f(8) substitute x = 8 into f(x)
f(8) = - 2(8) + 9 = - 16 + 9 = - 7
Similarly for g(- 1)
g(- 1) = (- 1)² - 2 = 1 - 2 = - 1
Then
f(8) + g(- 1) = - 7 + (- 1) = - 7 - 1 = - 8
Answer: 17
2^2 is 4
45/9 is 5
Multiply 4•5 to get 20
Subtract 3
To find the perimeter, you add up all the sides.
11 + 5 + 13 = 29
29 inches is the perimeter.
