Question

Simplify where possible. If it is not possible to simplify, explain why.

a) 3x + 6x

b) 2m + 5n

c) 5h + 8h + 2h

d) 7u + 4u + u

Answer 1

You can simplify a, c, and d.

Explanation:

a) 3x+6x=9x

b) 2m+5n (you cannot simplify since the variables are different)

c) 5h+8h+2h=15h

d) 7u+4u+u=12u

Hope this helps! :)
