The simplest expression is (2w)+(2*3w), because to calculate perimeter, you have to use this formula: 2length+2width.
8.
Slug: 101.6 centimeters every 30 seconds.
Slug is faster.
9. Use your conversion sheet, but your final answer is 15.9071 (Will vary depending on method)
Also, just to let you know your not supposed to put that many questions in one. They should be single.
It would be 98 degrees.
this is because on the top line their is a spot that we don’t know the angle of and next to it is an angle of 82 degrees and a line is equal to 180 degrees so all you have to do is subract 82 from 180.
hope this was correct & helped out

Step-by-step explanation:
Answer:
The function describes the motorboat's distance from the shore 
Step-by-step explanation:
A motorboat moves across a lake as a constant speed. when it begins, it is 50 km from the shore
After 9 minutes, it is 14 km from the shore.
So, rate of change = 
Negative sign shows that there is decrease in distance per minute
The rate of change of distance is 4 km / minutes
General equation : y = mx+c
Where m is the slope and c is the constant
Substitute the values in the equation :
y=-4x+50
Where y is the final distance and x is the minutes
So, Option C is true
Hence The function describes the motorboat's distance from the shore
