Select all answers that have a value of 32 A: 3x when x = 12 B: x + 8y when x = 8 and y = 3 C: 2x + 11y when x = 4 and y = 2 D: 4(y+1) when y = 7

Alright, lets try A. Since x = 12, we replace the x in 3x for 12. So that would make 3 * 12 What does that equal?

3*12=36 so not A

Yes, so let's try the next one. x + 8y when x = 8 and y = 3 So since x = 8 we replace that in the equation: 8 + 8y Since y = 3, we replace that in the equation too: 8 + 8 * 3 So the new equation is 8 + 8 * 3 You have to remember the order of operations for to solve this one.

Actually, you made a mistake while solving that. To solve 8 + 8 * 3, you have to multiply first. So start with 8 * 3, and then add.

Now let's check the other two since the question says to select all that apply. 2x + 11y when x = 4 and y = 2 So let's replace the x and y with their values. 2 * 4 + 11 * 2 Now remember to multiply first, and then add.
