Jamal has 2 straight sticks with lengths of 20cm and 18cm. Jamal searches for a third stick so that he can form a triangle. Which lengths of a stick will allow jamal to make a triangle.

A. 36 cm

Step-by-step explanation:

Let x represent the 3rd side length of triangle.

Please consider the complete question.

Jamal has 2 straight sticks with lengths of 20 cm and 18 cm. Jamal searches for a third stick so that he can form a triangle. Jamal searches for a third stick so that he can form a triangle. Which lengths of a stick will allow jamal to make a triangle.

A. 36 cm     B. 38 cm

C. 40 cm     D. 42 cm

We will use triangle inequality theorem to solve our given problem.

Triangle inequality theorem states that sum of measures two sides of triangle should me always greater than measure of 3rd side.  

We can set 2 inequalities as:

This means that third side of triangle should be greater than 2 and less than 38.

Since 36 is greater than 2 and less than 38, therefore, option A is the correct choice.

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.
