The Pythagorean Theorem states that "When a triangle has a right angle of (90°), the square of its hypothenuse is equal to the sum of the squares of the other two sides."
The hypothenuse is the longest side of the triangle.
For example: A triangle has 3 sides. Side A, Side B, and Side C (hypothenuse).
Side A = 3; Side B = 4; Side C = 5; To check if the theorem is true, we must square all sides.
Side A = 3² = 9; Side B = 4² = 16; Side C = 5² = 25
Pythagorean theorem: The square of the hypothenuse is equal to the sum of the squares of two sides.
<span>Side A² + Side B² = Side C² ==> 9 + 16 = 25 ==> 25 = 25</span>
In order to simplify this expression, we need to multiply the numeric values together and the variables together.
So we have:
Therefore the correct option is the third one.
Answer:
Root is x=16 Domain and Range would be all real numbers

Answer:
Yes, a ratio can be simplified.
Step-by-step explanation:
An example of this is 5:10, where it can be simplified down to 1:2.
Answer:
The velocity is 8.93 meters/second.
Step-by-step explanation:
It is given that Elena runs for 28 seconds and finishes at 250 meters.
Here the displacement is 250 meters and the time is 28 seconds.
We know that 
Substitute displacement = 250 and time = 28 in above formula.
meters/second
Hence, the velocity is 8.93 meters/second.
