Which side lengths form a right triangle? Choose all answers that apply:
A √2, √3, √4
B √8,3, √17
C 5,6,8

B. √8, 3 and √17 form a right triangle

Explanation:

√8², 3² and √17² satisfy a²+b²=c²

√8²+3² = √17²

8+9=17

The answer is B. Because 8 , 3, 17 add up to the length of a triangle

For this case we have the following expression:
 24 + 56
 The factors of the numbers are:
 24: 1, 2, 3, 4, 6, 8, 12, 24
 56: 1, 2, 4, 7, 8, 14, 28, 56
 So, factoring we have:
 24 + 56 = 8 (3 + 7)
 Simone wrote:
 24 + 56 = 8 (4 + 7)
 Therefore his error is:
 Simone did not use the correct factors for 24 in the equation
 
 Simone did not use the correct factors for 24 in the equation
