Johnny rewrites the expression as the expression shown below. Explain why this statement is or is not equivalent to the original expression.

2x^2 - (3x+3)

No, they are NOT equivalent because if you distribute the negative sign, the last number will be positive 3 and in the original expression it is -3.
No, they are NOT equivalent because if you simplify that expression, you get -6x at the very end and that is not in the original expression.
Yes, they are equivalent because if you simplify the expression, you get a 6x at the end and the original expression has a 6x.
Yes, they are equivalent because if you distribute the negative sign, you get -3x and -3 and that is the same in the simplified original expression .

No, they are NOT equivalent because if you distribute the negative sign, the last number will be positive 3 and in the original expression it is -3.

which of the following is equivalent expression to 1/2 (9 - 7^0) +(-29^0)

Yes, they are equivalent because if you distribute the negative sign, you get -3x and -3, which is the same as in the simplified original expression.

No, they are NOT equivalent because if you distribute the negative sign, the last number will be positive 3 and in the original expression it is -3.
