The solution in radical form

Rewrite as:

Using the quadratic formula, we have:

Where
a = 1
b = -10
c = -6
So, we have:



Split the roots

Express
as 2

Split the fraction


The base of the prism is a 3:4:5 right triangle.
One of the legs is its base and the other is its height. (The longest side is the hypotenuse!)
The area of the triangular base is bh/2 = (9)(12) / 2. There are two of these.
There are also three rectangular sides on the prism.
Their dimensions are 9 by 20, 12 by 20, and 15 by 20.
You can do the arithmetic from here.
And the answer is 828cm ^2
Answer:
3.2 feet
Step-by-step explanation:
The equation
shows the height of water [
] and horizontal distance [
].
<em>Given the </em><em>horizontal distance is 4 feet</em><em>, they want to know the height.</em>
<em>Simply put 4 in
of the equation and solve for
. So,</em>
<em>
</em>
So, the height of the water was 3.2 feet above the ground.
