Ill casapp some 5 if they get this right and show work.

they forget the last step which is to take the square root of the sum

7) a = 4

b = 17

a² + b² = c²

4² + 17² = c

16 + 289 = c²

305 = c²

√305 = c

17.464249196572980 = C

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
