Answer:
44, 6, and 24 are not perfect square
Step-by-step explanation:
Perfect square are numbers that can be square rooted with a result of a perfect whole number.
√16=4
√44= 6.63324...
√81= 9
√6= 2.44948...
√49= 7
√24= 4.898997...
7
the side length of the largest square is x
2x-1=3x-8
-x=-7
x=7
1.4 times as long
3 1/2 (convert to mixed number) --> 7/2
2 1/2 (convert to mixed number) --> 5/2
(7/2) / (5/2) --> 7/5 --> 1.4
now, there are 12 months in a year, so 18 months is really 18/12 of a year, thus
Answer:a: y=4.5+0.75x
B: y=2.5+1.25x
C: 7.5
