What is -7m-5(m+5)=-85

m= 5

Step-by-step explanation:

-7m-5(m+5)= -85

-7m-5m-25= -85

-12m-25= -85

-12m= -60

/-12     /-12

m= 5

m=5

Step-by-step explanation:

−7m−5(m+5)=−85

−7m+(−5)(m)+(−5)(5)=−85

−7m+−5m+−25=−85

combine the like terms: (−7m+−5m)+(−25)=−85

−12m+−25=−85

add 25 to both sides : −12m−25+25=−85+25

divide both sides by -12

−12m /−12  =  

−60 /−12

m=5

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
