Evaluate if t=2 and x=3:
3(2x2 – t)

30

Step-by-step explanation:

I used PEMDAS for this equation. Since t = 2 and x = 3, we need to replace the variables with the given numbers first in order to evaluate the expression:

3(2*3*2 - 2)

Next, use PEMDAS to solve.

Parenthesis: (2*3*2) = 12 - 2 = 10

Multiply: 3*10 = 30

Hopefully I did it right, wasn't sure if you multiply the x with the twos or not :)
