To solve this problem, we have to find how long it will take the bullet to travel 5,000 meters. We know that it travels 200 meters per second.
Therefore, if you divide 5,000 meters/200 meters per second, it will give you how many seconds it will take the bullet to travel 5,000 meters.
5,000/200 = 25
Therefore, it will take 25 seconds for the bullet to travel 5,000 meters.
So to solve this you need to reverse factor this problem
x^2 + 8x + 7 = 0
The common formula is this for factoring ax^2 + bx + c
Now you have to think what multplties to "c" and adds up to "b".
So in this case it's 7 x 1 = 7 and 7 + 1 = 8
So you set it up like this
(x + 7)(x + 1) = 0
So now you can check the factors by multiplying them together and see if it gets your original equation which is does.
So finally to get the answers you need to set each parenthesis to 0 and solve for x.
x + 7 = 0
x + 1 = 0
and we get x = -1 and - 7
You can also plug these two answers back into your original equation to see if it equals 0.

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.
