Answer 1

D and E

Explanation:

A= √6+√9

=2.44948974278+3

=5.44948974278

B= √64+6/11

=8+0.5454545455

=8.5454545455

C= √36+√21

=6+4.58257569496

=10.582575695

D=√16+√169

=4+13

=17

E=17.43+√49

=17.43+7

=24.43

F=√44+√25

=6.63324958071+5

=11.6332495807

Answer 2

Which statements about square roots are true? Check all that apply.

The square root of a positive number cannot be negative.

All positive numbers have two square roots.

StartRoot 18 EndRoot= 9 because 9(2) = 18.

StartRoot 49 EndRoot= 7 because 7(7) = 49.

StartRoot 25 EndRoot = 5 because 52= 25.
