(2a^2b + 3ab^2 - b^3) - (4b^3 - 3ab^2 -6a^2b)

skelet666 [1.2K]

<em>Hi there!</em>

<em>~</em>

<em></em> $(2a^2b+3ab^2-b^3)-(4b^3-3ab^2-6a^2b)$ <em></em>

<em>Distribute the Negative Sign:</em>

<em></em> $= 2a^2 b + 3ab^2 - b^3 + -1(4b^3 - 3ab^2 - 6a^2b)\\= 2a^2 b + 3ab^2 + - b^3 + -1 (4b^3) + -1 (-3ab^2) + -1 (-6a^2b)\\= 2a^2 b + 3ab^2 + -b^3 + -4b^3 + 3ab^2 + 6a^2 b$ <em></em>

<em>Combine Like Terms:</em>

<em></em> $= 2a^2 b + 3ab^2 - b^3 + -4ab^3 + 3ab^2 + 6a^2 b\\= (2a^2 b + 6a^2 b) + ( 3ab^2 + 3ab^2) + (-b^3 + -4b^3) \\= 8a^2 b + 6ab^2 + -5b^3$ <em></em>

<em>Answer : </em> $8a^2 b + 6ab^2 + -5b^3$ <em></em>

<em>Hope this helped you!</em>

Dot got a 75% on her test. She missed 12 questions. how many questions were on the test

AleksAgata [21]

Well, if it was out of 50, it would be 76%.

So the answer might be 50 questions total, but maybe there was 49 questions total.

I would probably go with 50 questions total.
