Question

if x +1=5 what is the value of x+2

Answer 1

Hii friend,

X+1 = 5

X = 5-1

X = 4

Therefore,

X+2 = 4+2 = 6

Hence,

X+2 = 6

HOPE IT WILL HELP YOU.... :-)

Answer 2

well, remember (a+b)^2=a^2+2ab+b^2 
Let's square the question given, that gives you x^2+2*x*(1/x)+(1/x^2)=25 
since 2*x*(1/x)=2,then 
x^2+(1/x^2)=25-2=23
