I need work to be shown as well

If f(x) = 6x – 4, what is f(x) when x = 8? a2 b16 c44 d52

Solve 4 ln x=2ln25 a) x=5 b) x=25 c) x=625

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
