Answer:
76
Step-by-step explanation:
16 + |-21 - 44| - 5
16 + 65 - 5 = 76
<span>So we want to know the number from which we take 65% and get 39. If the number we are looking for is x, then the equation to find that x would be: (65/100)*x=39 which says sixty five percent out of x is equal 39. So, x=(39*100)/65. And finally, x= 3900/65=60. So, 65% out of 60 is 39.</span>
Answer:
Question #1: Option C, (x - 1)(x^2 + x + 1)(x + 1)(x^2 - x + 1)
Question #2: Option C, 8x^3−56x^2+12x−84
Step-by-step explanation:
Question #1
<u>Step 1: Factor</u>
p(x) = x^6 - 1
<em>p(x) = (x + 1)(x - 1)(x^2 + x + 1)(x^2 - x + 1)</em>
<em />
Answer: Option C, (x - 1)(x^2 + x + 1)(x + 1)(x^2 - x + 1)
Question #2
<u>Step 1: Expand</u>
p(x) = 4(x - 7)(2x^2 + 3)
p(x) = (4x - 28)(2x^2 + 3)
p(x) = 8x^3 + 12x - 56x^2 - 84
<em>p(x) = 8x^3 - 56x^2 + 12x - 84</em>
<em />
Answer: Option C, 8x^3−56x^2+12x−84
