Step-by-step explanation:
Changes made to your input should not affect the solution:
(1): "x3" was replaced by "x^3". 2 more similar replacement(s).
((3•(x2))+(9•(x2)))-3x3
((3 • (x2)) + 32x2) - 3x3
(3x2 + 32x2) - 3x3
Pull out like factors :
12x2 - 3x3 = -3x2 • (x - 4)
-3x^2 • (x - 4)
Estimate by rounding both numbers to the nearest ten.
164 rounds to 160.
219 rounds to 220.
160+220=380
Final answer: 380
So, the answer is -8/15 .
I think the answer is 11 and 12 but my calculations could be incorrect.
