Question 1

1.

1. Andre says that 10x + 6 and
5x + 11 are equivalent because they both equal 16 when x = 1.
Do you agree with Andre?

Yes, I agree with Andre

No, equivalent expressions are equal no matter what value you plug in for the variable.  When you plug in 0, these expressions are not equal.
