Lonna is cutting construction paper into rectangles for a project. She needs to cut one rectangle that is 15 inches × 13 1 3 inches. She needs to cut another rectangle that is 10 1 4 inches by 10 1 3 inches. How many total square inches of construction paper does Lonna need for her project?

Lonna need 1046877 square inches of construction paper for her project.

Step-by-step explanation:

Dimensions of one rectangle = 15 x 1313 inches

Area = 15 x 1313

= 19695 square inches

Dimensions of another rectangle = 1014 x 1013 inches

Area = 1014 x 1013

= 1027182 square inches

Total construction paper needed = 19695 + 1027182

= 1046877 square inches

Lonna need 1046877 square inches of construction paper for her project.

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.
