Does anyone know how to do this?

2m²

to find the area of the □ find the area of the 2 triangles in it the height is 1m and the base is 2m

so do b×h not devided by 2 so you can also find the area of the other triangle so 1x2= 2

three-fourths of an hour

36÷48=0.75

0.75=

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.
