The measure of x is:

9 inches

Step-by-step explanation:

Perimeter = x + 2(x-4)

perimeter = 19 inches

then:

19 = x + 2(x-4)

19 = x + (2*x) + (2*-4)

19 = x + 2x - 8

19 = 3x - 8

19 + 8 = 3x

27 = 3x

27/3 = x

x = 9 inches.

where's the diagrams?

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
