{2(x+4) - 4.2(x+1)}/{2(x+2) ÷ 2} = ?
Solution
Correct Answer: Option A
{2(x+4) - 4.2(x+1)}/{2(x+2) ÷ 2}
= {2(x+4) - 22 .2(x+1)}/{2(x+2) × 2-1}
= {2(x+4) - 2(x+3)}/{2(x+1)}
= (2x . 24 - 2x . 23)/(2x . 21)
= {2x (24 - 23)}/(2x . 21)
= (16 - 8)/2
= 8/2
= 4
= {2(x+4) - 22 .2(x+1)}/{2(x+2) × 2-1}
= {2(x+4) - 2(x+3)}/{2(x+1)}
= (2x . 24 - 2x . 23)/(2x . 21)
= {2x (24 - 23)}/(2x . 21)
= (16 - 8)/2
= 8/2
= 4
