To find this you first have to find the f(x) values for x = 5 and x = 8
x = 5
f(x) = 5^2 + 6(5) + 11
f(x) = 25 + 30 + 11
f(x) = 66
x = 8
f(x) = 8^2 + 6(8) + 11
f(x) = 64 + 48 + 11
f(x) = 123
Then you subtract the two from each other to see how much it has changed in those 3 numbers.
123 - 66 = 57.
Then you take that answer and divide it by the change in x (which is 3)
57/3 = 19
It would be : 0.35 , 0.4 , 0.7 .
Hope This Helps You!
Good Luck Studying :)
Easy peasy pumpin easy
split it up (make in to net and unfold or something)
2 triangles (identical)
2 side rectangles (identical
1 base
area of rectangle=lh or wl etc
area of triangle=1/2bh
triangles
b=16
h=6
area of triangle=1/2*16*6=48
times 2 since 2 of them
48*2=96
2 side rectangles
10 by 7
10*7=70
times 2 since 2 of them
70*2=140
base
16by 7
16*7=112
add them
96+140+112=348
answer is C
The answer is 94.6 I hope this helped and you didn’t find the answer yet
Sorry I can’t read that hand writing if I could just write it on brainly
