4. A rectangle has length 3x + 4 feet. Its width is 7x feet. What is an expression in simplest form for the perimeter of the rectangle?​

2(3x+4)=P(perimeter)

Step-by-step explanation:

what I did was:

write out the expression 3x+4+7xcombine like terms in this case it's 3x and 7x10x+4put it in parentheses and put a 2 on the left side indicating distributive property for the equationit 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 equationequation should look like this: 2(10x+4)=P
