2square root of 5 is a) 2 and 3 b) 4 and 6 c) 6 and 9 d) 9 and 12

B as the square root of 5 is 2.5 ( 2.5 x 2.5 = 5) so five being between four and six, the answer is B

B
Because 2 sqrt5 is = to sqrt 20.

4^2=16, 6^2=36

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
