Recall the formula for the area of a trapezoid, A=12h(a+b) , where h is the height and a and b are the lengths of the parallel sides. Find the area of this trapezoid. I NEED THE ANSWER FAST PLSS!!

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.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
