To answer this, first, you need to multiply the first bracket to the second bracket. Then, it will show like this: 4x(3x^2)-4x(2x)+4x(1)-2(3x^2)-2(-2x)-2(1)= 12x^3-8x^2+4x-6x^2+4x-2.
Then simplify them by adding or subtracting the same objects (same exponents and same variables). If they don't have the same objects, just let them be.
The final answer will be: -12x^3-14x^2+8x-2

<span>The correct answer is 12x</span>³<span>-14x</span>²<span>+8x-2.

Explanation:
We use the distributive property:
4x*3x</span>² <span>- 4x*2x + 4x*1 - 2*3x</span>² <span>- 2*(-2x) - 2*1 = 12x</span>² <span>- 8x</span>² <span>+ 4x - 6x</span>² <span>+ 4x - 2.

Combining like terms, we have 12x</span>³<span>-14x</span>²<span>+8x-2.</span>

Strike441 [17]

Answer: 25 + 3n

Step-by-step explanation:

Hi, the answer is lacking the last part:

<em>Write an expression for the amount of money he makes this week. </em>

So, to answer this we have to write an expression:

The fixed amount that he earns per week (25) plus the product of the amount he earns per subscription (3) and the number of subscriptions sold (n) , must be equal to his weekly earnings.

Mathematically speaking:

25 + 3n
