Answer: The simplified form by combining like terms is given by

Step-by-step explanation:
Since we have given that

Now, we combine the like terms :
1) First we collect m terms :

2) Combine n terms and constant terms :

Hence, the simplified form by combining like terms is given by

<span>f(x) =6x +4 replace x with 10 and solve
f(x)= 6(10) + 4
f(x) = 64</span>
