Answer: The answer is 56
Step-by-step explanation: If you do 4x2 because she takes 4 tablets twice a day which means she takes 8 tablets a day and if we do 8x7 because there are 7 days a week which means she take 56 tablets a week. If that makes any sense. c:
Answer:
5x³ + 5x² - 55x - 15
Step-by-step explanation:
simplify the expression:
5(x − 3)(x² + 4x + 1)
use the distributive property to multiply 5 by x-3
(5x - 15) (x² + 4x + 1)
Use the distributive property to multiply 5x−15 by x²
+4x+1 and combine like terms
5x³ + 5x² - 55x - 15

The linear regression equation obtained by fitting the data using a regression model is :
ŷ = -0.017X + 6.03
From the regression plot, the relationship between the two variables, speed and lifetime is negative, that is an increase in one variable will lead to a corresponding decrease in the other.
