Asap ! add 4p^2+6 / 4p^2 + 2p-2 / 10p which statements are true about adding the rational expressions? check all that apply the least common denominator is 20p . the first fraction rewritten with the lcd is 20p^2+30 / 20p^2 the second fraction rewritten with the lcd is 4p - 4 / 20p the sum is 24p^2-,4p+30 / 20p^2 = 12p-2p+15 / 10p^2 the sum is a rational expression.
