Choose the true biconditional statement that can be formed from the conditional statement "If the area of a square is 25 square meters, then the
side length of the square is 5 meters" and its converse.

A. A biconditional cannot be formed because the statement and its
converse are not logically equivalent.
B. If the side length of a square is not 5 meters, then the area of the
square is not 25 square meters.
C. The side length of a square is 5 meters if and only if the area of
the square is not 25 square meters.
D. The area of a square is 25 square meters if and only if the side
length of the square is 5 meters.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
