Mario claims that a rhombus is sometimes a square, but a square is always a rhombus. Is he correct?Explain.

yes

Step-by-step explanation:

he is correct because a square is always a rhombus because one of the def of a square is a rhombus with  right angle. a rhombus is not always a square because rhombuses do not have to have right angles. they only need to have adjacent sides congruent and be a parallelogram. it can be a rhombus without right angles, so Mario is correct. if a rhombus does have right angles, (sometimes it will) then it will be a square.

you cant answer this dummy

step-by-step explanation:

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.
