Answer 3

To simplify the given expression, we'll start by performing the operations step by step.

Expression: -9x(y + 7 + y)

Step 1: Combine like terms within parentheses Inside the parentheses, we have y + 7 + y. Combining like terms, we get 2y + 7.

Step 2: Rewrite the expression after combining like terms Now the expression becomes: -9x(2y + 7)

Step 3: Distribute the -9x to the terms inside the parentheses To do this, we multiply each term inside the parentheses by -9x:

-9x * 2y = -18xy -9x * 7 = -63x

Step 4: Combine the results of the distribution The final simplified expression is:

-18xy - 63x

So, the simplified expression for -9x(y + 7 + y) is -18xy - 63x.
