Answer:
A
Step-by-step explanation:
Okay cool, so basically the formula is a^2 + 2a square root a square over 4 + h square.
We have to us e the Pythagorus theorem to find the height.
3^2 + h^2 = 36
9 + h^2 = 36
h^2 = 27
h ~ 5
Let's plug in the values from the formula.
The closet answer should be A
I can give you an example:
4x^2+2xy-3y^2
it is in the form of :
x^2+2ax+a^2
also : (x+a)^2 = x^2+2ax+a^2
I believe you work the problem out and put the answer down.
Answer:
ok
Step-by-step explanation:
whats the question?
After solving for x1, we get
Step-by-step explanation:
Given formula is:
In order to solve for x1, we have to isolate x1 on one side of the equation
So,
Multiplying the whole equation by 2:
Subtracting x2 from both sides
so,
After solving for x1, we get
