Let the number be a .... =>Number doubled : 2a .. =>Eight less than the no. Doubled : 2a - 8 =>Eight less than the no. doubled is 20 more than the no. : 2a - 8 = 20 + a =>2a - 8 - 20 - a = 0 =>2a -a - 20 -8 = 0 =>a -28 = 0 =>a = 28 =>so the number is 28... Hope it helps!!!

Given that $f(x) = 3x^2 + 5$ , we have

$f(x + 3) = 3 (x + 3)^2 + 5 \\\\= 3 (x^2 + 6x + 9) + 5 \\\\= 3x^2 + 18x + 32$

so that

$f(x+3) - (f(x) + 3) = (3x^2 + 18x + 32) - (3x^2 + 8) \\\\= \boxed{18x + 24}$
