Use the diagram and information to answer the question. Given:AB∥CD
m∠A=104∘
m∠B=76∘
Prove:Quadrilateral ABCD is a parallelogram

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.
