Answer:
12√2.
Step-by-step explanation:
You can do this by the Pythagoras theorem:
20^2 = x^2 + (4sqrt7)^2 where x is the distance required.
x^2 = 20^2 - (4sqrt7)^2
= 400 - 112
= 288
x = √288
= √144 *√2
= 12√2.
If it has a number before the fraction, it is between that and the next number, if not, it is between 0 and 1. if it is negative, it is between 0 and -1 with the above rules, just if it is only negative
