HERE'S THE ANS

ok try to find out VSD devisions which you can find out very simply.... least count = MS count/ total VSD so you get total vernier scale division as 10 now its given that for new caliper main scale division is 0.6 mm . Standrd caliper has value 1 mm so if you divided 23.1 by 0.6 you will get 38.5 38 comes from main scale division  so 0.5 has to come from VSD which point on VCD is nearer to any MSD? so divide .5 by 0.06 that will be VCD

i need good explantion

i have made the correction

(m+1)x² + 2mx+5x +m+3 = 0 has equal roots............ find the value of m.

give a ans with solution............. rates for sure!!!!!!!!!!!!!!!!!!

DON'T MIND THAT INEQUALITY SIGN............ JUST GIVE THE RATE LAW

2 SO₂ + O₂   ( greater than or equal to) 2 SO₃ (g)

PLEASE SAY THE RATE LAW FOR IT.

please someone ans this question...................

ans with steps please

i need answers with steps

(1)   1/4x+4 > 2/4x-2

(2) x²+5x+3/x+2 < x

 please give me a answer with detalied solution. rates for sure
