Lol no one is going to work that out just copy and paste into an online calculator good luck
A number line can be used to find the difference because you can count from 28 to 34 and the number you get will be your answer.
Answer:
Consider the expression
. q is called the quotient, a is is the dividend and b is the divisor.
Since q is a multiple of 6, then q has the form
for some integer k.
Since a is a multiple of 9, then a has the form
for some integer s.
Since b is a factor of 12, then if 12 can be expressed of the form
, for c an integer. Then b has the form 
Replacing the preview expression in the initial expression we obtain:

Then
is a equation to Isabel's problem.
The area of the polygon with vertices W (1, 1), X (4, 4), Y (7, 1), and S (4, −8) is 36.
Have a great day! :D
