Question

1. Combine like terms to simplify the expression.
5x + 4 + 2x + 5 .


2. Use the distributive property to factor the expression.
2k + 10 .

I am really confused on these two questions. Can someone help me out?
5x + 4 + 2x + 5
= 5x + 2x + 4 + 5
= 7x + 9

2k + 10
can you think of a number that will divide evenly into 2k and into 10?
Is it 5?
