There are six important properties of parallelograms to know:
<span>Opposite sides are congruent (AB = DC).Opposite angels are congruent (D = B).Consecutive angles are supplementary (A + D = 180°).If one angle is right, then all angles are right.The diagonals of a parallelogram bisect each other.<span>Each diagonal of a parallelogram separates it into two congruent triangles.</span></span>
8(n +5n +6) is the correct anwser
Let's add the fractions first and then we can estimate the sum.
= 31/4 + 17/3 + 8/18
change to common denominators
= 279/36 + 204/36 + 16/36
add numerators only
= 499/36 or 13 31/36 or 13.86
ANSWER: (B) 13 is the best estimate of the answer. Normally we round up to 14 with a number like 13.86, but since that is not a choice, we can estimate 13 as the answer.

Answer:6.5
Step-by-step explanation: If you simplify (3 x 2) into 6, it will leave 6+6x=45. So if you subtract 6 on both sides it will cancel out the one on the left and make 45 into 39. So now you have 6x=39 so now you just divide 6 on both sides and get 6.5.
