Answer: $-2x^3-14x^2+7x-4$

Step-by-step explanation:

$(3x^3-2x^2+4x-8)-(5x^3+12x^2-3x-4)$

Distribute the negative sign.

$(3x^3-2x^2+4x-8)-5x^3-12x^2+3x+4$

Remove the other parentheses.

$3x^3-2x^2+4x-8-5x^3-12x^2+3x+4$

Combine like terms.

$-2x^3-14x^2+7x-4$

1 km = 1000m
so 4 km = 4(1000) = 4000 m

so Kali runs 4000 m per day
4000/400 = 10 laps per day

for 3 days = 3(10) = 30 laps for 3 days
