Now,<u> ALGEBRAIC IDENTITY </u>states that
= 
Here, comparing a = r and b = s, we get
= 
So, the first blank has the value r.
Second blank has the value 2
Answer:
No
Step-by-step explanation:
To determine if the 3 sides form a right triangle.
Use the converse theorem of Pythagoras.
If the square of the longest side is equal to the sum of the squares of the other two sides then the triangle is right,
longest side = 14 and 14 ² = 196
9² + 12² = 81 + 144 = 225
Since 196 ≠ 225 the triangle is not right
6 times because you find the common denominator which is 8 so 3/4 is 6/8. He needs to fill his cup 6 times.
