This is a guess, but, from what I've researched, maybe decrease? I've looked into it alot and that's just I think, though, it may depend on the previous height. Still, just an educated guess (I've got 100% on all kinds of quizzes because of educated guesses so, it may work!)
A. Put these answers into your table :
5, 6.20, 7.40, 8.60, 9.80
B see pic
c yes there is a linear relationship between the letters and cost
D the equation is y=.60x+5
He would notice that the numbers are starting at two and increasing by 2 each time. Also, all the numbers are even.
The pattern is that you are simply counting by 2's.
2, 4, 6, 8, 10, 12, ....
Answer:
ok so if we take length to be x we know width is x-3
the perimeter is the total length of sides, if you look at a rectangle you can see it has 4 sides with 2 length and 2 width. so perimeter is 2 times (x + x-3) = 26.
2x -3 = 13, 2x = 16, x = 8, 8 is length
the width is then 8-3 = 5.
Length = 8, width = 5.
