Which is expression is equivalent to 4b

1.b(8-4)= b(4) = 4b

2. b(2+2)= b(4) = 4b

3. b(6-2)=b(4)=4b

Step-by-step explanation:

This problem bothers on our understanding of algebraic expression and its equivalent

4b is such an expression

To find it equivalent we have

Say

1.b(8-4)= b(4) = 4b

2. b(2+2)= b(4) = 4b

3. b(6-2)=b(4)=4b

We can go on and on. The list is endless so long as we the right factors of 4 under check.

The best way to get a hold on this is to understand your factors very well

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.
