Evaluate 3x^2 + 5y + 7 if x = -2 and y = 3
thanks in advance
Put in those values, and compute. I will be happy to critique your thinking.
3(-2)^2 + 5(3) + 7 = ?
Please indicate your subject as math rather than your grade level.
I hope this helps. Thanks for asking.

To evaluate the expression 3x^2 + 5y + 7, substitute the given values of x and y into the expression and simplify.
Given: x = -2 and y = 3
Step 1: Substitute the values of x and y into the expression.
3(-2)^2 + 5(3) + 7
Step 2: Simplify the expression inside the parentheses.
3(4) + 5(3) + 7
Step 3: Simplify the multiplication.
12 + 15 + 7
Step 4: Add the numbers together.
12 + 15 + 7 = 34
Therefore, when x = -2 and y = 3, the expression 3x^2 + 5y + 7 evaluates to 34.
