Perimeter is how far around, so you are going to total the 2 lengths and 2 widths. A way to write that is P=2l+2w.
P = 2(5 5/8) + 2 (6 1/4)
2(5 5/8) = 10 10/8 or 11 2/8 or 11 1/4
2(6 1/4) = 12 1/2
P = 11 1/4 + 12 1/2
P = 23 3/4
It's a little fuzzy to read, but I'll try my best.
Difference is subtraction, so you measure how big both squares are and subtract them for the difference. As for the median, I think it'd be the line in the middle of both squares.
As for the box-a-whisker, I don't exactly understand.
Answer:
The second number is four more than, two times the first number. The third ... Start by writing an expression for each of the three numbers. They are all formed from the first number, so let's call the first number x . Let the first number be x. The second number is 2x+4. The third number is 3x−5. We are told .

Answer: 
Step-by-step explanation:
You need to draw a right triangle as the one attached, where 
is the angle of elevation from the fire to the top of the fire tower.
You need to use the Inverse trigonometric function Arctangent:
Observe the triangle. You can identify that:
Then, you can substitute values:
Finally, evaluating, you get that the angle of elevation from the fire to the top of the fire tower is the following:
Rounded to the the nearest tenth of a degree:
Scientific notation is another way to write a number. In scientific notation, the letter E is used to mean "10 to the power of." For example, 1.314E+1 means 1.314 * 101 which is 13.14 .
