Part A The area is L times W so (6x^2+3x-2)(x^3-2x+5) so you times like terms since 6x^2 and x^3 has no like terms it ends up like this x^3+6x^2-6x-10 that is the area Part B and Part C i dont know im sorry
For a number to be divisible by 6, it must also be divisible by 2 and 3. Therefore, we need to check if a number is even and then check if the sum of the digits is divisible by 3.
