Answer:
9m(n)^3 +14m(n)^2
Step-by-step explanation:
6m(n)^3 - m(n)^2 + 3m(n)^3 + 15m(n)^2
=> 6m(n)^3 + 3m(n)^3 + 15m(n)^2 - m(n)^2
=> 9m(n)^3 +14m(n)^2
Answer:
4.41
Explanation:
13.17 - 8.76 = 4.41
Answer:
x = 7
Step-by-step explanation:
Set the equations equal to each other, since the two angles are congruent.
x + 16 = 4x - 5 now solve
21 = 3x
x = 7
Answer:
x = 6/4 or 1 1/2
Step-by-step explanation:
4x+3=9
Subtract the 3 from both sides
4x+3=9
-3 -3
4x = 6
Divide both sides by 4
x = 6/4 or 1 1/2
