Find 3x^2 - y^3 - y^3 - z if x = 3, y = -2, and z = -5.

Numerical Answers Expected!
I got 92, is that right?

Answer 1

Pretty sure it's wrong though lol

Answer 2

nope...not really

Answer 3

I got 48

Answer 4

I think it is wrong

Just break it down...

What is 3x^2 if x=3

What is y^3 if y= -2

don't forget you are subtracting y^3 in the equation....

Answer 5

\[3x^2-y^3-y^3-z\]
so, we substitute
\[3(3^2)-(-2^3)-(-2^3)-(-5)=3(9)-(-8)-(-8)-(-5)\]
\[27+8+8+5=48\]

Answer 6

o3o welp I'm going to submit this lol

Answer 7

Answer 8

My reply was to your first answer of 92 - sorry for confusion.
