7(3x^2-6x+2)
21, 42, 14 they can be divided by 7 so we put 7 out
9 miles
use Pythagoras theorem
15 squared - 12 squared = 81
square root of 81 is 9
look at the picture shown
An irrational number is a number that has no pattern and has no end. For example 3 divided by 7 is an irrational number because of the lack of pattern and never-ending decimal.
