Question

Use the drop-down menus to complete each statement to show why 5sqrt(7) is between 10 and 15.

Answer 1

First drop down: √4 and √9

Second drop down: 2 and 3

Third drop down: 10 and 15

Explanation:

the root of four is 2

the root of nine is 3

thus √ 7 is between 2 and 3

5√7 is between 10 and 15 because 2x5 is 10 and 3x5 is 15.
