Explanation:
6q + 4q:
To simplify this expression, you add the like terms (terms with the same variable, q in this case):
6q + 4q = (6 + 4)q = 10q
So, the simplified expression is 10q.
10(xy):
Here, you have a product of 10 and the variables x and y. To simplify, just multiply them:
10(xy) = 10xy
So, the simplified expression is 10xy.
4 + 3(x+3):
This is an expression with parentheses, so you need to apply the distributive property (also known as the FOIL method) to simplify:
3(x+3) means you distribute the 3 to both terms inside the parentheses:
3(x+3) = 3x + 33 = 3x + 9
Now, you add this result to the 4:
4 + 3x + 9 = (4 + 9) + 3x = 13 + 3x
So, the simplified expression is 13 + 3x.
