Studdy Solution

STEP 1

Assumptions1. The given expression is (7m+7)+(6m+5)(7 m+7)+(6 m+5). We are looking for expressions that are equivalent to the given expression

STEP 2

First, we simplify the given expression by combining like terms. Like terms are terms that have the same variables and powers. The coefficients do not need to match.
(7m+7)+(6m+5)=7m+6m+7+5(7 m+7)+(6 m+5) =7m +6m +7 +5

STEP 3

Now, we add the coefficients of the like terms to simplify the expression further.
7m+6m+7+5=13m+127m +6m +7 +5 =13m +12

STEP 4

Now, we compare the simplified expression with the given options. The first option is 13m+1213 m+12, which is the same as our simplified expression.

STEP 5

The second option is 13m+7+513 m+7+5. This expression is not equivalent to our simplified expression as it has not been fully simplified. If we simplify it, we get 13m+1213m +12, which is equivalent to our simplified expression.

STEP 6

The third option is (+m)+(5+6m)(+ m)+(5+6 m). This expression is equivalent to our simplified expression if we rearrange the terms and combine like terms.

STEP 7

The fourth option is 7m+(7+6m)+57 m+(7+6 m)+5. This expression is equivalent to our simplified expression if we rearrange the terms and combine like terms.
So, the expressions equivalent to (7m+7)+(6m+5)(7 m+7)+(6 m+5) are 13m+1213 m+12, 13m+7+513 m+7+5, (7+7m)+(5+6m)(7+7 m)+(5+6 m), and 7m+(7+6m)+57 m+(7+6 m)+5.
