1. Find the product of the following:

-5x-4y-7(-8x-6y-8 - 9 x3y9 + 4x2y-11)

= (-5x-4y-7)(-8x-6y-8) - (-5x-4y-7)(9 x3y9) + (-5x-4y-7)(4x2y-11)

= 40x-10y-15 + 45x-1y2 - 20x-2y-18

2. Perform the following division:

56.4 X 10-7

1.88 X 10-6

= 30*10-7+6

= 3

3. Perform the following division:

x+7

x2 - 18x - 175 = x2 - 25x + 7x - 175 = x(x - 25) + 7(x - 25) = (x + 7)(x - 25)

So,
