Answer:
yourself 1 ticket.
16 left
3 friends x 5 tickets ,=15
16-15= 1
Just my thought.
Unless you don't go. Then your remainder is 2. But, it said share not give away. So I am thinking you keep a ticket.
So sneaky
Good luck
Area of triangle=1/2 times base times height
height=3 times base
h=3b
so
area=54
54=1/2bh
subsittue 3b for h
54=1/2b(3b)
54=(3/2)(b²)
times both sides by 2/3
36=b²
sqrt both sides
6=b
sub back
h=3b
h=3(6)
h=18
the heigh is 18cm
The answer is u=4
u(2+u)-2u=16
2u+u^2-2u=16
The 2u's cancel out
u^2=16
You find the square root of u^2 and 16 which leaves you with
u=4
All points in which the y-value is the 4x the x-value so some points are
(1,4)
(2,8)
(3,12)
(4,16)
(5,20)
etc.
This is due to the fact the the perimeter of a square is always 4 times any side, since all sides are equal
