Find 3x2 - y3 - y3 - z if x = 3, y = - 2, and z = - 5

35. You have to plug in all the numbers to the matching variables and solve.

The answer would be 35

u multiply the 3 and 3 then multiply the 2 then u take the - 2 and then u multiply to get the - 6. then do the same for the other one. then u get 18 + 6+6+5=35

the subtraction signs turn to plus.
