Answer:
-6i
Step-by-step explanation:
Complex roots always come in pairs, and those pairs are made up of a positive and a negative version. If 6i is a root, then its negative value, -6i, is also a root.
If you want to know the reasoning, it's along these lines: to even get a complex/imaginary root, we take the square root of a negative value. When you take the square root of any value, your answer is always "plus or minus" whatever the value is. The same thing holds for complex roots. In this case, the polynomial function likely factored to f(x) = (x+8)(x-1)(x^2+36). To solve that equation, you set every factor equal to zero and solve for the x's.
x + 8 = 0
x = -8
x - 1 = 0
x = 1
x^2 + 36 = 0
x^2 = -36 ... take the square root of both sides to get x alone
x = √-36 ... square root of an imaginary number produces the usual square root and an "i"
x = ±6i
Started out with 32/32. They ate 18/32, 32-18=14; 14/32. To simplify, 7/16 was left.
Answer:
67 im pretty sure because the other vertical is 45 and then 67-22=45 so hope this helps.

Answer:
83 1/3 words per minute
or approximately 83 words per minute
Step-by-step explanation:
4 pages * 250 words/ page = 1000 words
1/5 hour * 60 minutes/ 1 hour = 12 minutes
1000 words / 12 minutes = 83.333333333.... words per minute
83 1/3 words per minute
