Best ResponseYou've already chosen the best response.1well ok.. we can combine like terms first to make it easier \[2r^2r^2r^2+3s^3+4t^2\] \[2r^22r^2+3s^3+4t^2\] \[3s^3+4t^2\] s=3 t=5 \[3(3)^3+4(5)^2\] \[3(27)+4(25)\] \[81+100=19\]

Best ResponseYou've already chosen the best response.1True, but if OP has a closed book closed note test... then what? The only way to solve it is the manual way.

Best ResponseYou've already chosen the best response.1these sites that automatically solve the problem for you are only supposed to be used to check your answer... it shouldn't be a replacement to do the math the pencil and paper way.

Best ResponseYou've already chosen the best response.1This is called the substitution principle: An expression maybe replaced by another expression that has the same value.

Best ResponseYou've already chosen the best response.14 + 2 can be replaced by 6 because they have the same value 4 + 2 = 6. Similarly, if x = 6, then x can be replaced by 6 because they have the same value 6 = 6.
