your welcome
I'm not 100% sure on the first one but on the second I can help you out. How would you characterise the relationship? All it is, is that the more hours were spent studying, the higher the score will be.
Paul's function. Since the x values are hours of study all you must do is sub 3 for x in the equation giving you y = 8(3) + 40 = 24 + 40 = 64
What does the 40 mean? This in a straight line is the y-int so all its saying is that no matter how much study Paul does, he will at least get 40 marks.
Hope this helped :)

Answer:

Step-by-step explanation:
Hello There!
The first thing we need to do is find the formula for area of a trapezoid
The formula is
where a= base 1
b = base 2
and h = height
we are given all of the dimensions so all we have to do is plug them in
sp
so the area of the figure is
32 units ²
Answer:
shortest: 33 feet
second: 66 feet
third: 58 feet
Step-by-step explanation:
s = shortest side (33)
2s = second side (66)
25 + s = third side (58)
157 = s + 2s + 25 + s
157 = 4s + 25
4s = 132
s = 33
