<h2>12x^3 - 14x^2 + 8x - 2 = 2(6x^3 - 7x^2 + 4x - 1)</h2>

(4x-2) (3x^2-2x+1)

Multiply the first term from the first bracket by every term in the second bracket:

4x* 3x^2 = 12x^3

4x * -2x = -8x^2

4x * 1 = 4x

Multiply the second term from the first bracket by every term in the second bracket:

-2 * 3^2 = -6x^2

-2 * -2x = 4x

-2 * 1 = -2

Add the results together:

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

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

12x^3 - 8x^2  - 6x^2 + 4x + 4x - 2

<h2>12x^3 - 14x^2 + 8x - 2</h2>

Find a common factor to simplify:

Common Factor = 2

Divide everything by 2.

<h2>2(6x^3 - 7x^2 + 4x - 1)</h2>

HELP PLEASE <br> Write the inequality that models the number granola bars (12) you need to buy.
Goshia [24]
The correct question in the attached figure

Let
x-------------> <span>the number of granola bars 
y-------------> the pounds of fruit

we know that

if 12 bars------------> cost $12
 1 bars--------------> X
X=12/12---> x=$1
1 bar---------> cost $1

if 9 pounds of fruit----------> cost $36
 1 pound-------------------> X
X=36/9--------> x=$4
1 pound -------> cost $4

</span><span>expression for the total cost=(1)*x+(4)*y----------> x+4y
</span><span>x=12
y=9
then
</span>the total cost=12+4*9----- $48

<span>an inequality that compares
the total cost with the amount you have to spend is
x+4y<=48
</span>
using a graph tool see the attached figure

<span>the inequality that models the number of granola bars you need to buy is
</span>
x<=12  the solution for the number of granola bars is the interval [0,12]

40% of<br> a number is 8 more than the<br> number<br> Which is the number
salantis [7]
Do you mean 8 more smaller if so the answer to your question is
X+y=40
Y=8 + x
Substituting the second equation into the first:
X+(8+x)=40
2x+8=40
2x=32
Smaller number: x=16
Y=8+(16)
Large number: y=24
