Combine any like terms in the expression. If there are no like terms, rewrite the expression. 9d3 + c2?

Step-by-step explanation:

Simplifying

Step 1

9d3 + c2  If we try to combine like terms, it wont work because the exponents and its coefficients are different so we cant simplify or combine further  

So therefore There are no like terms.

Hope this helps

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.
