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)
two intersecting lines can only have 1 solution.
Answer
B) x + 20 ≥ 50

Answer:
y=2x+4
Step-by-step explanation:
8=2(6)+b
8=12+b
4=b
Answer:
the answer would be 81
Step-by-step explanation:
6 to the second power would be 36 then you would multiply 36x2 and it would equal 72. then you would do 2x6 which is 12. then 72+12-3= 81
