I only one person rode a tricycle - that would leave 23 wheels and you cannot make a complete number of bicycles
If 2 people rode tricycles that would leave 20 wheels which would seat 10 bicyclists.
But that totals up to 12 people
3 people riding tricyles leaves 15 wheels which will not complete a number of bicycles
4 people riding tricycles (4 x 3) leaves 14 wheels for 7 bicyclist and is the answer
4 trike riders (12 wheels) + 7 bike riders (14 wheels) = 11 people and 26 wheels
112/14=x/20
Cross multiply.
14x=2240
x=160
Therefore, at this rate, Leanne would chew 160 pieces of gum in 20 days.
Answer:
True: B, C and D
Step-by-step explanation:
The graph of the function is shown in the attached diagram.
The vertex of the parabola (parabola is the graph of the function f(x)) is at (-3,-16), because

So, option A is false and option B is true.
As you can see from the graph, the function is increasing for all x>-3, thus option C is true.
The graph is positive for x<-7 and x>1 and negative for -7<x<1, so option D is true and option E is false.
