Answer:

#2a+14#

Explanation:

You use the Distributive Property. This property states that a constant (which, in this case, is #2#) multiplied by an expression in parentheses or brackets (this is the #a+7# part for your problem) is the constant multiplied by every term in the expression.

Put into math, the Distributive Property looks like this for your problem:

#(a+7)2#

#=a(2)+7(2)#

#=2a+14#
