2 divides both numbers, so divide both numbers by 2 to get 3 and 7. These are relatively prime, so 2 is the gcd. The lcm is 6*14/2=42.

<span>There are 9 books on the shelf. 0 are blue and the rest are green how many books are green

THE ANSWER IS 9
You'd use the equation a^2 + b^2 = c^2 (**** ^2 means squared****)
a = 60
b = 11
c = ?
60^2 + 11^2 = c^2
3600 + 121 = c^2
3721 = c^2
then just square root 3721 and c^2
c = 61 feet
