Use the distributive property to remove the parentheses.
2(7+u)
2 ( 7 + u ) = 2 ∙ 7 + 2 ∙ u = 14 + 2u

To remove the parentheses using the distributive property, we need to distribute the 2 to both terms inside the parentheses, 7 and u.
So, we multiply 2 with 7 and 2 with u:
2 * 7 = 14
2 * u = 2u
Therefore, using the distributive property, 2(7+u) becomes:
14 + 2u
