How can you use mental math to determine that 28,000 divided by 70 equals 400?
Ann [662]
Hello! First I would just look at the numbers without the zeros. So 28/7. This equals 4. Next cross out the same number of zeros on each side of the equation. In this instance, the 7 has one zero and the 28 has three so you can cross out one zero on each side. This leaves you with two zeros left over to add to the end of the 4. So you end up with 400. 

I hope this helps!

morpeh [17]

Answer:

C. -7x^2-28x

Step-by-step explanation:

The given expression is 4x(3x-7)-19x^2

We apply the distributive property to expand the parenthesis

12x^2-28x-19x^2

Regroup similar terms to get:

12x^2-19x^2-28x

Combine the similar terms to obtain:

-7x^2-28x

The correct option is C.
