Hey!
You must divide the amount of money he spent by the amount of money each ticket costs:
32 ÷ 8 = 4
So, Mr. Chen bought 4 tickets.
20 and 7 Because 4x5 = 20
The domain is the set { -2, 0, 2, 3}
discussion:
the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives -2, 0, 2, 3.
To find the perimeter of any shape, you find the sum of their side lengths.
In this case, this triangle has side lengths of 1.197, 0.764, and 1.74.
Add these, and the sum is your answer.
1.197 + 0.764 + 1.74 = 3.701
Therefore 3.701 is the correct answer :)
There least common factor would be 5 since they are all divisible by 5.
