Answer:
The answer is [tex]-22k-67m[/tex]
Step-by-step explanation:
In order to determine the answer, we have to know about adding similar terms. A term consists basically in a variable and its coefficient. In an expression, we can find differents terms, where every term has a different variable.
If there are similar terms, it means, the same variable, we can add them.
Firstly, we multiply the factors with the parentheses and then we add similar terms:
[tex]8(k+m)-15(2k+5m)\\8k+8m-30k-75m\\(8k-30k)+(8m-75m)\\-22k-67m[/tex]
We can see two terms (k and m variables).
Finally the equivalent expression is [tex]-22k-67m[/tex]
