For an acid the formation of a hydrogen ion denotes it as being acidic.HCL -> H+ + CL-Where as for an alkali the formation of a hydroxyl ion denotes is as being alkaliNAOH -> Na+ and OH-

Integration is the opposite of differentiation.First of all take your 2x³ So in differentiation you would times the power by the coefficient and then minus one from the power.This would give,6x...

First label your two simultaneous equations1)2x+y=42)3x+2y=6Then rearrange 1)1*) y=4-2xNow sub 1*) into 2)3x + 2(4-2x)=6and expand brackets and solve for x3x+8-4x=6-x=-2x=2Now sub x=2 into 1)2(2)+y=4y=0
