Use the distributive property to multiply -2x by -4x and -9. 
-2x(-4x - 9) = (-2x * -4x) + (-2x * -9) 
= 8x^2 + 18x When multiplying two negative numbers together, the result is positive. Therefore, -2x(-4x - 9) simplifies to 8x^2 + 18x. The answer choice that matches this simplified expression is C.
