Answer:
1. Equivalent2. Not equivalent
Step-by-step explanation:
1. Equivalent because there's 4 x's that you add all together and that makes 4x2. Not equivalent because 5x means there's 5 x's or x + x + x + x + x not only 1 x plus a number 5
1. is equivalent. if you add the variables X, it'll be equal to 4x
2. It is not equivalent . 5x means 5 multiplied by X. x+5 means the unknown number X is added to 5, not multiplied. So it is not equivalent
