if there are 4 numbers that average to 60, when mutiplied they must come up to: 60*4= 240
100+30+45= 175
240-175= 65
PROOF:
100+30+45+65= 240
240÷ 4
= 60
Answer:
The last choice 2x^3 - 18x.
Step-by-step explanation:
(fg)(x) - f(x) * g(x)
= (x^2 - 9)(2x)
= 2x^3 - 18x.
For this case we have the following expression:
-2x ^ 2 (x + 5) + x (2x ^ 2-10x) + x
Rewriting we have:
-2x ^ 3 - 10x ^ 2 + 2x ^ 3 - 10x ^ 2 + x
Grouping terms with the same exponent:
x ^ 3 (-2 + 2) + x ^ 2 (-10 - 10) + x
-20x ^ 2 + x
Rewriting:
x (-20x + 1)
Answer:
The simple form of the expression is:
x (-20x + 1)
200 because the more trials, means the more accurate the results are! Hope this helps
Idk what the ! are for but i would thing the answer is 2...
