Answer:

A.) x3 - 6x2 + 5x + 12

Step-by-step explanation:

FOIL (First, Outer, Inner, Last)

(x-4)(x2-2x-3)

Distribute the x to everything in the other parentheses

x * x2 = x3            x * -2x = -2x^2          x * -3 = -3x

Distribute the -4 to everything in the other parentheses

-4 * x2 = -4x^2       -4 * -2x = 8x         -4 * -3 = 12

Combine like terms

x3 + -2x^2 - 3x - 4x^2 + 8x + 12

x3 - 6x2 + 5x + 12

Answer: FIRST OPTION

Step-by-step explanation:

You must keep on mind that, according the exponents properties, when you multiply two powers with equal base, you must add the exponents.

Then:

- Apply the distributive property as you can see below:

(x*x^2)-(x*2x)-(x*3)-(4*x^2)+(4*2x)+(4*3)=x^3-2x^2-3x-4x^2+8x+12

-Add like terms, then you obtain:

x^3-2x^2-3x-4x^2+8x+12\\x^3-6x^2+5x+12

Someone help w these tw
Bumek [7]

1. The simplified expression is 10x+8y-12.

Combine like terms to simplify the expression.

-6x-12+8y+16x

-6x and 16x are both like terms, so those can be combined.

-6x+16x=10x

10x+8y-12

2. The solution to the equation is x=13.

Solve by adding 17 to both sides of the equation.

-4=-17+x

-4+17=-17+17+x

13=x
