If my math is right it should be B)
If you are not familiar with the Pythagorean theorem, I will write it below to remind you for your future mathmatical endeavours:

c is the hypotenuse, and a and b are the other two sides. The hypotenuse is the largest side of a triangle. In this example, a and b are equal to each other and c is equal to 2, so I'm going to convert b into a and do some math trickery here:


Basically, I swapped b with a and combined like terms. Then I just replaced c with 2, then squared it into 4.
All you have to do now is solve for a
Step 1 is to divide both sides by 2 to get:

Then just square both sides:

Now you know that the length of the sides are equal to the square root of 2.
Sorry if this was a bit rushed, I hate running out of time on these. If you have any questions on why I did something, ask away in the comments.

since the points fall on some of the same rows and columns, you can figure each side is 5 units (probably centimeters) apart. Area =SideOne×SideTwo and 5×5=25
The nearest percent increase in 53 to 68 is about 29 percent.
Answer:
It would be best if Peter's report card percentage was based on<em> </em><em>the mean</em><em> </em>and if he could drop a percent, he should drop the <em>44%</em><em>.</em>
<em />
Step-by-step explanation:
The median (without dropping a score) of this set would be 75%
( 44%, 64%, 71%, 75%, 84%, 90%, 98% )
The mean (without dropping a score) of this set would be 75.1428571%
526 ÷ 7 = 75.14 ( 7<em>5.1428571 </em>)
