Choose the correct product of (5x + 4)2.
25x2 + 40x + 16
25x2 − 16
25x2 + 16
25x2 − 40x + 16

25x^2 + 40x + 16

Step-by-step explanation:

(5x + 4)^2

= (5x + 4)*(5x + 4)

= 25x^2 + 20x + 20x + 16

= 25x^2 + 40x + 16

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.
