Kelly completed the following calculation on her homework. X2 = 64
X= +32
Kelly's mom checked her homework and told her she needed to correct that answer.
Part A: Explain using a geometric example why Kelly would need to correct her answer.
Part B: Revise Kelly's calculation, and explain why the revised answer is correct.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

1. a^4+8a^3+24a^2+32a+16

2.y^8+8y^7+28y^6+56y^5+70y^4+56y^3+28y^2+8y+1

3.x^6-3x^4y^2+3x^2y^4-y^6

the answer for the second equation is (4,0)
