Answer:
3,060
Step-by-step explanation:
Given:
18C4
nCr=n! / r!(n-r)!
=18! / 4!(18-4)!
18!=18*17*16*15*14*13*12*11*10*9*8*7*6*5*4*3*2*1
=6,402,373,705,728,000
4!=4*3*2*1
=24
(18-4)!=14!
=14*13*12*11*10*9*8*7*6*5*4*3*2*1
=87,178,291,200
18! / 4!(18-4)!
=6,402,373,705,728,000 / 24*87,178,291,200
=6,402,373,705,728,000 / 2,092,278,988,800
=3,060

Answer:
x = 4
Step-by-step explanation:
Distribute parenthesis on both sides of the equation
4x + 4 = 6x - 4 ( subtract 6x from both sides )
- 2x + 4 = - 4 ( subtract 4 from both sides )
- 2x = - 8 ( divide both sides by - 2 )
x = 4
