Answer:
-39
Step-by-step explanation:
The expression in this problem is
[tex]3x^3 - 3y[/tex]
We want to evaluate this expression when
[tex]x=-3[/tex]
[tex]y=4[/tex]
Substituting into the expression, we find:
[tex](-3)^3 - 3(4) = \\-27 - 12 = \\-39[/tex]
Because
[tex](-3)^3 = (-3)(-3)(-3) = -27[/tex]
and
[tex]3\cdot 4 = 12[/tex]
And this expression is a polynomial, which is an expression consisting of more than one algebraic terms (in this case, two of them)
