40(8) + (2(12))(8) + 200
320 + 24(8) + 200
520 + 192
712
Answer: B. 712
Firstly,we need to understand the properties of a parallelogram:
-Opposite sides are parallel by .
-Opposite sides are congruent.
-Opposite angles are congruent.
-The diagonals bisect each other.
Therefore in this case:
XW must be congruent to YZ.
WZ must be congruent to XY.
Hope it helps!

Since no real values are given for the angles, we will not have an exact angle measurement.
If ∠LPQ is x+28, then that means ∠NPM is the same, since they are vertical angles.

Since ∠QPM is x, then ∠LPN is also x, because they are also vertical angles.


Answer:
40.5g of salt is left after evaporating all the water.
Step-by-step explanation:
Here, 9% of 450g means that out of 450 gram of solution, 9% is the salt.
So, we need to calculate 9% of 450
i.e. 9% * 450 = 0.09 * 450 = 40.5g
Hence, 40.5 grams of salt is in 450 grams of solution.
i.e. 40.5g of salt is obtained after evaporating all the water from the solution.
