10x=100 because tbh if you Calculate 5x-10=40 it’s give you your answer and go off of that.
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)
The trick here is to notice that all 3 terms can be div. by 2:
2(x^2 + x - 12)
Note that -12 factors into -3 * 4 or -4 * 3. Thus,
x^2 + x - 12 = (x-4)(x+3), and so <span>2x2 + 2x − 24 = 2(x-4)(x+3).</span>
