Answer:
Conjugate radicals.
Step-by-step explanation:
The two roots a+sqrb and a-sqr b are called conjugate radicals.
Unlike the previous problem, this one requires application of the Law of Cosines. You want to find angle Q when you know the lengths of all 3 sides of the triangle.
Law of Cosines: a^2 = b^2 + c^2 - 2bc cos A
Applying that here:
40^2 = 32^2 + 64^2 - 2(32)(64)cos Q
Do the math. Solve for cos Q, and then find Q in degrees and Q in radians.
Answer:
D. X-7
Step-by-step explanation:
The table tells you that when x=7, g(x) = 0. In order for g(7) to be zero, at least one factor must be zero when x=7. The only factor on the list that is zero when x=7 is (x-7).
Answer:
Step-by-step explanation:
x² + 9x+8 = (x+1)(x+8)
