F(11) means to replace x in the equation with 11
12(11) + 5
12 x 11 = 132
Now you have 132 + 5 = 137
F(11) = 137
Answer:
-0.37
Step-by-step explanation:

-----------------------------------------------------
L*W*H , So 4*4*4, So therefore it would be 64 m3
1. It's a sine relationship => sinA = 25 / 34 => A = 47.
2.It's a cosine relationship => cosA = 26 / 35 => A = 42.
