Question

Evaluate x3 - 3y when x = -3 and y = 4 what is this?

Answer 1

Answer:

-39

Step-by-step explanation:

The expression in this problem is

$3x^3 - 3y$

We want to evaluate this expression when

$x=-3$

$y=4$

Substituting into the expression, we find:

$(-3)^3 - 3(4) = \\-27 - 12 = \\-39$

Because

$(-3)^3 = (-3)(-3)(-3) = -27$

and

$3\cdot 4 = 12$

And this expression is a polynomial, which is an expression consisting of more than one algebraic terms (in this case, two of them)
