Answer:
That's what I think the answer is
CB = CA - AB
= -8 - 29
= -37
Note that
a² - b² = (a+b)(a-b)
i² = -1 by definition.
We want to factorize x² + 36 = x² + 6².
Consider the expression
x² - (6i)² = x² - (6²)(i²) = x² - 36i² = x² + 36
Because x² - (6i)² = (x + 6i)(x - 6i)
Therefore
x² + 36 = (x + 6i)(x - 6i)
Answer: (x + 6i)(x - 6i)
Answer:
the answer is A. 99 degrees because 81 + 18 = 99
