The manatee is 12.60$ for the clearance price.
So its 20t+1.75 because each ticket is 20 dollars, so when you substitute 3 into t, the answer is 61.75
The sides of an equilateral triangle are equal length, so ...
GH = FH
3x-9 = 2x-2
x = 7 . . . . . . . . add 9-2x
Then the side lengths are
FG = x+5
FG = 7 +5 = 12
x = 7
FG = GH = FH = 12
-2 + 4x - 4
= 4x-6
Make sure to distribute everything and then combine like terms.
Answer: 4x-6
