I would choose A. Samantha is testing the actual question "how many LIBRARY books are checked out by 7th graders at SAME time". She is still getting a result to the question, but an inaccurate reading as we do not know if ALL 7th graders are present in library and she is only doing a portion of 7th graders checking out books. However, Luis is going to cafe and some may never have gone to library or dislike reading tangible material. Basically both are bad surveyors, but Luis is definlately performing a more random approach.

Will the solution of an equation such as x-3=9 be a variable on a number? Explain

X= 12
Add three on both sides to get rid of it
9+3 and -3 + 3 the three is negative because you drop the minus sign down
This cancels out the three and 9+3 is 12 so X=12

That's an easy parallelogram, parallel to the x axis. Let's label the points

A(-4,-1),B(-2,4),C(4,4),D(2,-1)

AD and BC are the sides parallel to the x axis. We'll call those the base, it has length 4 - -2 = 6.

The height is the change in y between the bases, so 4 - -1 = 5.

The area is base times height, 6 × 5 = 30

Answer: 30

The shoelace formula gives us the area of a polygon from 2D coordinates without worrying about the shape:

(-4,-1),(-2,4),(4,4),(2,-1)

(-2,4),(4,4),(2,-1),(-4,-1)

A = \frac 1 2 | -4(4) - (-1)(-2) + (-2)(4) - 4(4) + 4(-1) - 4(2) + 2(-1) - (-1)(-4) |

A = \frac 1 2 |-60| = 30 \quad \checkmark
