-2.
You have to get rid of the 10, so you add 10. After you add ten, you add 10 to the 2. Now, your left with -6x=12. -6x divided by -6= 2, so 12–6=-2

Answer:
20x⁵ + 20x⁴
Step-by-step explanation:
Use distributive rule: a*(b +c) =a*b + a*c
5x⁴(4x + 5) = 5x⁴ * 4x + 5x⁴ * 5
= 20x⁵ + 20x⁴
Hint: 5x⁴ * 4x multiply the coefficient and then the variables. For multiplying variable, if they two have same base, then add the powers
5*4 * x⁴ * x = 20x⁵
5 x (m + 2)
Or if you are factoring, then you do this, 5 times m equals 5m + 5 times 2 which equals 10 so therefore you answer will be:
5m + 10
