Answer: The Pythagorean theorem is used to find a side. When you need to find c, a and b should equal it. Not any random number squares and then added together will make a random number squared equal.
Step-by-step explanation:
8% = 0.08
60 * (1 + 0.08) = $64.80
To solve this you need to know Pythagorean theorem.
First, EG is 24, so the halfway points are 12. Knowing Pythagorean triples, you can use 5,12,13 and 12,16,20.
DF = 5+16
DF = 21
If you don't know Pythagorean triples, I have worked it out on the image attached.
No because the perfect trinomial has a square as the third term and the middle term is a multiple of 2.
