Multiply (x-7) (x^2+2x+3)

x^3 - 5x^2 - 11x - 21

Step-by-step explanation:

(x - 7) (x^2 + 2x + 3)

use distributive property, basically means multiply

x^3 + 2x^2 + 3x - 7x^2 - 14x - 21

add like terms

x^3 - 5x^2 - 11x - 21

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
