You would first do 2 multiplied by 2x and that would give you 4x, then you would do 2 multiplied by 3y which would give you 6y, you would put 4x under 2x and put 6y under 3y and bring down your addition symbol
1. a (n) = -0.6(n) + 14.6

Y=2x+2 describe the best fit.
first find x and y intercept of a line
x intercept where y=0 is x=-1 and y intercept where x=0 is y=2
Short side length = x
Medium side = x + 7
Long side = 5x
Total 49, so
x + x + 7 + 5x = 49
If you combine like terms:
7x + 7 = 49
Subtract 7 from both sides
7x = 42
Divide both sides by 7
x = 6 inches
It will be $3.68 for each rose bush because if she bought 6 of them for $22.08 then 22.08/6=3.68
