Answer:
first option
Step-by-step explanation:
Given
(3x² + 2x - 3)(x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
3x²(x - 1) + 2x(x - 1) - 3(x - 1) ← distribute parenthesis
= 3x³ - 3x² + 2x² - 2x - 3x + 3 ← collect like terms
= 3x³ - x² - 5x + 3

Step-by-step explanation:
A dog owner records the weight of her dog. She finds that from the age of 20 weeks to the age of 48 weeks, the dog’s weight can be modelled by the equation

where
w = weight
t = number of week from 20 weeks to 48 weeks
If we want to extend this model to the dog's weight at birth, then find the dog's weigth when it was born.
At t = 0,

We get the dog's weight -0.15 kilograms at the day the dog was born. But this is impossible, because the dog's weight cannot be negative.
