The answer is 20, since it’s heads and tails you have a half and half chance, therefore you divide 40 in half and get 20
For the first one you need to do
x+2+x+2+2x+4+2x+4
=6x+12
When doing this kind of problem you should use FOIL
First, Outer, Inner, Last
(x+2)(2x+4)
First- x•2x= 2x^2
Outer- x•4= 4x
Inner- 2•2x= 4x
Last- 2•4= 8
Combined you have
=2x^2+8x+8
11y-5
11(1)-5
11-5
6
six is the answer
The correct answer is C. t= 8ln(100)
Hope this helped! :)

Answer:
The multiplicative rate of change is 3
Step-by-step explanation:
The given graph passes through the points:

The multiplicative rate of change is the factor that multiplies each y-value to give the subsequent y-values.
We can find that factor by dividing a y-value by the previous y-value of any two consecutive y-value.
The multiplicative rate of change is
