what is 9x another # and same of 8x 7x 6x 5x 4x 3xn and more
To find the sum of 8x, 7x, 6x, 5x, 4x, and 3xn, we need to add up all the terms:
8x + 7x + 6x + 5x + 4x + 3xn
To evaluate this expression, we combine like terms. Like terms are the ones with the same variables raised to the same powers. In this case, all the terms have the variable "x," so we can combine the coefficients (the numbers in front of "x"):
(8 + 7 + 6 + 5 + 4)x + 3xn
Now, let's simplify the coefficients:
30x + 3xn
So, the sum of 8x, 7x, 6x, 5x, 4x, and 3xn is 30x + 3xn.
