steps

1.√ ( − 3 − 9 ) ^2 + ( 5 − 5 ) ^2

           √ ( − 12 ) ^2 + 0

                   √ 144

                √ 144 ≈ 12

************************************************

2. √ ( 7 − (− 1) ) ^2 + ( 10 − 6 ) ^2

√ ( 7 + 1 )^ 2 + ( 10 − 6 ) ^2

√ ( 8 )^ 2 + ( 4 ) ^2

√ 64 + 16

√ 80 ≈ 8.94427190999916

round up to 8.9

*****************************************************

3. √ ( 6 − 0 ) ^2 + ( 0 − 8 ) ^2

    √ ( 6 ) ^2 + ( − 8 ) ^2

       √ 36 + 64

      √ 100 ≈ 10
