B. 4(3y+6) If you distribute 4 to 3y and 6 you will get 12y+24 However before doing the following solution solve the given expression first which is 12(y+2) You need to distribute 12 so the answer will be 12y+24, therefore 4(3y+6)=12(y+2)
E. 12(y)+12(2) In the expression stated you should multiply twelve to both y and 2 which is the same as 12(y+2) because you both distribute the 12 to both variable(y) and coefficient(2) which is the same as the given expression. Both answers are the same and is equal to 12y+24
