Ok this is not as hard as it seems
(4.5 feet)^2 times the number of students (13)
20.25 x 13
263.25 is the correct answer
I hope it helps :<
Step-by-step explanation:
4 times of 7 (7 + 7 + 7 + 7 = 28) is the same as 7 times of 4 (4 + 4 + 4 + 4 + 4 + 4 + 4 = 28)
4^7 (4 x 4 x 4 x 4 x 4 x 4 x 4 = 16384) is not the same as 7^4 (7 x 7 x 7 x 7 = 2401)
Answer:
2
Step-by-step explanation:
Use slope formula: (y2-y1)/(x2-x1)
(14-6)/(8-4) = 8/4 = 2
The gradient is 2
Answer:

Step-by-step explanation:
Given

Required
Determine the equation of line that passes through (-8,0) and parallel to 
Parallel lines have the same slope.
In 
The slope, m is

because the general form of a linear equation is:

Where

So, by comparison:

Next, is to determine the equation of line through (-8,0)
This is calculated using:

Where


So, we have:






Answer:
60 degrees
