In both the sets, 3 and m as well as n can be found as common factors.
So,
3mn( m+4n)
Therefore the answer is 3mn (#3)
<span>90 + 35 = 125.
180 -125 = 55 degrees.
4.59^2 + 6.55^2 = 8^2
21.1 + 42.9= 64 inches</span>
-3 + -3 = 0
-5 + 1 = -4
vector = < 0,-4 >
15% - 40. -25 = 1500 percent take out the zero because they have zero value and your left with 15 which is 15%
