Part A: Area = length * width = (6x^2 + 3x - 2) * (x^3 - 2x + 5) Multiply it out and simplify.

part B: Take the first term 6x^2 and multiply each of the term x^3, -2x & 5. Then take 3x and multiply each of the term x^3, -2x & 5. Do the same with -2. Then add like terms and simplify.

12 eggs cost $2.30 thus we divide by 12 to get the cost of one egg.

2.30/12 = 0.19166666666 per egg

Now the same for the 30 eggs.

5.50/30 = 0.18333333333 per egg

thus, 30 eggs for $5.50 are a better deal
