Let's start with triangle RST. This is a 30-60-90 triangle, which means it has the relationship x - x sqrt(3) - 2x.
If RS is 2 sqrt(3), then ST must be 2 and RT must be 4.
Triangle QRT is a 45-45-90 triangle, which means it has the relationship x - x - x sqrt(2).
If RT is 4, then RQ must also be 4.
Answer: x = 4
Hope this helps!

Answer:
8x² + 3x - 8
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x) = 6x² + 3x + 1 + 2x² - 9 = 8x² + 3x - 8
X² + 5x - 14 = 0
(x-2)(x+7) = 0
x - 2 = 0
x + 7 = 0
x = 2
x = -7
Your answer is B.
