The answer is no bc they all have the same x coordinate and therefore fail the vertical line test
Answer: 15
Step-by-step explanation: Use the formula: 
Remember
should always be the hypotenuse or the longest side.
---> evaluate the exponents
----> subtract 12544 to the other side
---> take the square root of both sides

For similarity measures of corresponding angles should be equal so we would use AA similarity postulate
x + 1/2 = 3/4
set denominators equal:
x + 2/4 = 3/4
-2/4 for both sides:
x = 1/4
there you go! hope this helps!
1) Well you divide the copies by 14 for the amount of friends that Ivan has helping him then multiply that to the 0.25 cents that he is playing them.
2) You multiply 1428 of the copies of flyers to the 0.10 then add that answer to the answer of number 1
