Given the expression
12m + 5(4-5m)
Applying the distributive property:
12m + 20 -25m
Combining like terms:
--------> -13m + 20
Then,
8 + 5g + 6(9g-2)
Applying the distributive property:
8 + 5g + 6*9g - 2*6
Simplifying:
8 + 5g + 54g - 12
Combining like terms:
--------> 59g - 4
The answers are:
-13m + 20 and 59g - 4
