√ 256 = √ 4 = √ 169 = √ 100 =

√ 121 = √ 196 = √ 16 = √ 64 =

√ 1 = √ 9 = √ 49 = √ 144 =

√ 225 = √ 81 = √ 25 = √ 36 =

112 = 132 = 142 = 102 =

122 = 12 = 152 = 62 =

92 = 32 = 42 = 162 =

82 = 72 = 52 = 22 =

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.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
