Question

Need help!! don't know what I'm doing

Answer 1

Answer: 4 squared + 2 squared is the least, 5 squared is in the middle, 6 squared - 6 is the greatest

Step-by-step explanation:

least in total=20

middle in total=25

greatest in total=30

Answer 2

Step-by-step explanation:

Here,

1st expression:

${6}^{2} - 6 = 36 - 6 = 30$

2nd expression:

${4}^{2} + {2}^{2} = 16 + 4 = 20$

3rd expression:

${5}^{2} = 25$

Hence, the order from least to greatest is,

20 < 25 < 30

Also,

$( {4}^{2} + {2}^{2} ) < {5}^{2} < ( {6}^{2} - 6) \: \: (ans)$
