Answer:
(2x)X-12
Step-by-step explanation:
x-6.x-2
So firstly, what two terms have a product of 8x^2 and a sum of 9x? That would be x and 8x. Replace 9x with x + 8x: 
Next, factor x^2 + x and 8x + 8 separately. Make sure that they have the same quantity on the inside: 
Now you can rewrite the equation as 
Now using zero product property, solve for x:

<u>In short, the solutions are {-1,-8}, or C.</u>

Answer:
154000
Step-by-step explanation:
2: 2 * 2 * 2 * 2 = 16
5: 5 * 5 * 5 = 125
7: 7
11: 11
composite number := 16 * 125 * 7 * 11 = 154,000
86.4+86.39 divided by 2=86.395
