I believe the answer would be the bottom left one
Whatever is inside of the ( ), simply plug that digit into the x-values for f(x)
So: f(x) = 7x - x^2, and f(7+h) - f(7)
= [7(7+h) - (7+h)^2] - [7(7) - (7)^2]
= [49+7h - 49+14h+h^2] - [49-49]
= 49-49 + 7h+14h + h^2 = h^2 + 21h =
h (h+21), h (h+21) = 0
h=0... But it stated h cannot = 0
So h+21 = 0, h = -21
Answer:
66
Step-by-step explanation:
PEMDAS (parenthesis is first)
14-8=6
15-4=11
then you multiply
6 times 11 equals 66
30000mm÷10=3000cm
3000cm÷100=30m
Answer: 30m
