The twenty dash twotwenty-two members of the mathematics club must send a delegation to a meeting for student groups at their school. the delegation can include as many members of the club as desired, but at least one member must attend. how many different delegations are possible?

The number of subsets of a set of 22 elements is 2^22 = 4,194,304. This count includes the empty set, which is the one delegation that is not allowed.

There are 4,194,303 delegations possible.

the anwser is d) 75°

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
