Answer:
-30
Step-by-step explanation:
f(x) = 3 so f(-8) = 3;
g(x) = 5x + 7, so g(-8) = 5(-8) + 7 = -33
Then (f + g)(-8) = 3 - 33 = -30
This is the sum of two functions both evaluated at x = -8.
6/14=x/20 cross multiply and get 14x=120 divide and get 8 2/30
The one you have highlighted is correct, that is the sign for congruent.
Answer: 9.5, 7
9.5 , 8.5
Step-by-step explanation:
Answer:
Yes, because P = 2x +2(12)
Step-by-step explanation:
As the formula for perimeter is 2(L+B).
Let L=x=18
B=12
Then, perimeter, P=2(18+12) = 2(30) = 60
Hence, we get the perimeter as 60 units.
