The radius is 4.99, im sure
Answer:
(c)
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos42° =
= 
Multiply both sides by 12
12 × cos42° = x, hence
x ≈ 8.9 → (c)
-4^4= -4*-4*-4*-4
-4*-4=16
16*-4=-64
-64*-4= 256
Final answer: 256
First step is to distribute.
-4a^2 - 6a +2 + 3a^2 -3
Combine like terms
-a^2 -6a -1
