Step-by-step explanation: its A. the denominator has to be the same as the hypotenuse
Answer: 113.04
Step-by-step explanation: The equation for the area of a circle is pi r squared so you have to find the radius first. To find the radius, find the diameter first. A way to do this which was easiest for me was dividing 37.68 by pi (3.14), which is 12. Divide the diameter by 2 to find the radius, 6.
Now use the equation from the beginning, pi r squared. So plug in pi as 3.14, then the radius as 6. It is important to always square the radius first, which would be 36. Now multiply 36 by 3.14, and there should be your answer.

Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
(x₁, y₁) - point
We have the equation:

Therefore we have
the slope m = -2/3
and the point (-9, 5)
A slope

rise = -2
run = 3
From the point (-9, 5) ⇒ 2 units down and 3 units to the right.
Answer: 1) 
2) 55 points
Step-by-step explanation:
1) A= 8w + 18, w=1.25
A = 8(1.25) + 18
A = 10 + 18
A = 28ft^2
2) 25 points to start with, additional 5 points per magazine they sell, m = number of magazines they sell
total points = 25 + 5m
How many if they sell 6?
total = 25 + 5(6)
= 25 + 30
total = 55
