2,000 (3,500-300=3,200. 3,200 - 1,200 = 2,000)
Is there a picture or something of some sorts?!?
Start with the second expression. That factors easily into (8x-3)(8x+3).
Since 64x^2 + 48x + 9 has no negative signs, I'd bet that the common factor is (8x+3). Divide <span>64x^2 + 48x + 9 by that to verify.

Answer:
112.6°
Step-by-step explanation:
Using cosine law:
20² = 11² + 13² - 2(11)(13)cos(A)
110 = -286cos(A)
cos(A) = -5/13
A = 112.6198649
