8. Just substitute 5 for the n in the formula.

20 2x = 2 times x
2y = 2 times y
multiply those together gives you 2 * x * 2 * y = 4xy

22 means How many whole numbers are there between 5 and 9?

8 Put n=5 into n(n+3) = 5(5+3) = 40

20 it is 2x multiplied by 5y = 10xy

22 x is greater than 5 and less than 9. So x could be 6, 7 or 8.

9 You subtract the 3 from the 9 = 6

10 (4,3)

17 180 - 65 - 65 = 50 degrees

27 B is approximately one third of the semi-circle. So the answer is 60 divided by 3 = 20
