Объяснение:

=6m^2+11m-7-6m^2-54=11m-61

Answer 2

To simplify the expression (3m + 7)(2m - 1) - 6(m² + 9), you can follow these steps:

Step 1: Distribute the terms in the first parenthesis (3m + 7) to the terms in the second parenthesis (2m - 1):

(3m + 7)(2m - 1) = 3m(2m) + 3m(-1) + 7(2m) + 7(-1)

Step 2: Simplify each term:

6m² - 3m + 14m - 7

Step 3: Combine like terms in the expression:

(6m² + 14m) + (-3m - 7)

Step 4: Combine like terms again:

6m² + (14m - 3m) - 7

Step 5: Further simplify:

6m² + 11m - 7

Now, your simplified expression is 6m² + 11m - 7.
