Step-by-step explanation:
by using Pythagoras theorem,
h^2= p^2+b^2
or, b^2=h^2- p^2
Answer:
Quadratic Equations! Yes!
Step-by-step explanation:
Now, there are three methods to solving this:
1.Quadratic Formula
2.Factoring
3. Completing the square
Now, Based on the answers, I think it would be better if we used Quadratic Formula, as you cannot get the answer easily with factoring, and I'm a bit rusty on completing the square.
So, Quadratic Formula! To solve it using this method, we have to find x using this:
(the +- before the square root means it could be both positive or negative)
Where a, b are coefficients and c is a term(in a quadratic equation form:
)
So, we just have to input the stuff from our equation into the formula!

Now, we can simplify the square root of 32 into 4 times the square root of 2

And, we can divide 2 from it all!

So, there you have it! The Answer is C, or 3.
Hope this helps!
