1. solve -a/-6+5 =2
2. 5(12-3p)=15p+60
3. 3(y-2) = 6(y-1) - 3y
4. 3a+21 = 7-4a
5. what i the solution set | 2x-3| =7

* answer by 11: 30 p. m.*

whatvare the choices

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb
