Answer:
The answer is (1,0) and (5,2)
Step-by-step explanation:
Since they are asking for parallel lines that means the slopes of the lines has to be the same line AB slope is 1/2 if you find the slope of (1,0) and (5,2) it will be the same as 1/2
Number of Neutrons = Atomic mass - Atomic number
= 16 - 7 = 9
In short, Your Answer would be 9

To find the area of a trapezoid, we use the following formula:

In this formula a represents the area and b1 and b2 each represent a base of the trapezoid.
So, we have got the following information



Filling in the formula gives us:



Finally we have to divide both sides by 15.

Therefore, the height of the trapezoid is 10 meters.
