Answer:
2(3x+4)=P(perimeter)
Explanation:
what I did was:
write out the expression 3x+4+7x
combine like terms in this case it's 3x and 7x
10x+4
put it in parentheses and put a 2 on the left side indicating distributive property for the equation
it should look like this so far 2(10x+4)
and you need to add what you are trying to find, so add =p to the right of the equation
equation should look like this: 2(10x+4)=P
