Ineed cause i'm really bad at math. ¯\_(ツ)_/¯here it goes: simplify the following expression: 6x + 2(3x - 9y + 5) + (-9)also can you give me tips on how to solve these problems? .someone answer my question.

ill explain better

Step-by-step explanation:

use distrubrity property and you get 6x + 6x -18y+6+(-9) then you add 18 because you have to get the y way so you do the opposite of subtracting which is adding so when you add the 18 to it self you then add the 18 to one of the 6x the you get 24x+6x+-4 which u add 6 to -9 the to combine like terms and get 30x+-4

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19
