Paul is solving for x. He shows his work as follows: Step 1: 3x + 2 = 7x - 2
Step 2: 2 = 4x - 2
Step 3: 4 = 4x
Step 4: X = 1
When Paul checks his answer, he thinks he’s made a mistake At which step did Paul make a mistake?

This is correct

Step-by-step explanation:

Paul has made no mistakes but he probably is wondering if the 4x that he got in the equation is correct.  He might second guess that he shouldn't have subtracted the 3x from the 7x but instead divided the two numbers.

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
