Rewrite in simplest terms: -2(8d+10f)-7f-10(-7f+7d)−2(8d+10f)− 7f−10(−7f+7d)

Classify each polynomial by its degree and by its number of terms.

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000

I’m stuck on this equation, anyone got the answer?
