27m^3+64n^3

1 answer:

8 0

27m^3+64n^3 is an example of the sum of two cubes.

There's a factoring formula for that: a^3 + b^3 = (a + b)(a^2 - ab + b^2.

Thus, 27m^3+64n^3 = (3m + 4n) ( 9m^2 - 12mn + 16n^2).

Could also find this out by dividing 3m+4n into 27m^3+64n^3.

5q - p + p + 1, please help!

So basically you just add the like terms to simplify the equation. You have 5q-p+p+1 you can cancel out the both p’s because one is negative and one is positive. That leaves you with 5q + 1 they are not like terms so you cannot simplify them so your simplified equation is 5q +1
