Answer:

$\large\boxed{A.\ -10x^2-33x+1}$

Step-by-step explanation:

$6x(x-4)-16x^2-(9x-1)\qquad\text{use the distributive property}\\\\=(6x)(x)+(6x)(-4)-16x^2-9x-(-1)\\\\=6x^2-24x-16x^2-9x+1\qquad\text{combine like terms}\\\\=(6x^2-16x^2)+(-24x-9x)+1\\\\=-10x^2-33x+1$

if we're factoring you can use the AC method. A multiplied by C is 24. and 4x6 is 24.

(x+4)(x+6) is your answer

Simplify the expression by combining like terms:<br><br> 4n+4(2n+3)

Anna007 [38]

First, you do the distributive property on:

4(2n+3)

You would get

8n+12

Then add the original part of the equation in (4n)

4n+8n+12

Combine like terms

12n+12 is the answer
