Questions Math 1. Sue please 1. First, we notice that the expressions in a and d can be rewritten so that they do not contain parentheses. We now only have to check c and e. So c and e are not equivalent to a , b , and d. For c , we can use the distributive property and decompose one of the numbers to write two equivalent expressions:.
For e , we can add and subtract the same number or the same term to write two equivalent expressions:. Explain your answer. Here, the terms 2 y and 5 y are like terms. So, add their coefficients. Use the Distributive Law to expand the first expression. The first expression is the sum of 2 x 's and 3 y 's whereas the second one is the sum of 3 x 's and 2 y 's. Let us evaluate the expressions for some values of x and y. So, there is at least one pair of values of the variables for which the two expressions are not the same.
They are not equivalent in general.
