Don’t mind my answer...it’s wrong pls help

If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (cxd)(x)

Ataxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile, or f = $2.25 + $0.20(m - 1) where f is the fare and m is the number of miles. if juan's taxi fare was $6.05, how many miles did he travel in the taxi? if juan's taxi fare was 7.65, how many miles did he travel in taxi

Which value would be a solution for x in the inequality 47-4x< 7
