Answer:
2x^2(3x^2-2x-1)
Step-by-step explanation:
12x^4 - 8x^3 - 4x^2
everything is a multiple of 4 so divide the whole thing by 4
12x^4 - 8x^3 - 4x^2/4= 3x^4-2x^3-1x^2
write it in disturbed form
2(3x^4-2x^3-1x^2)
now if u see we can see that the X will be same, so we also have to factor it out and 2 is the exponent that all can give
2x^2(3x^2-2x-1)
Answer:
1. 
2. x = 16
3. Part 1: P is the independent variable and S is the dependent variable.
Part 2: x is the independent variable and y is the dependent variable.
Step-by-step explanation:
1. To write the function notation for:
Sales tax is 7% of the total price.
Let the total price be
.
And sales tax be
.
As per the given statement:

Writing it in the function notation:

2. To find the value of x such that
and

Putting the value of 

3. To find the dependent and independent variable.
Independent variables are those whose value is not dependent on the other variable's values.
Dependent variables are dependent on the value of other variables.
In question 1:

P is the independent variable.
S is the dependent variable.
In question 2:
If we write it as follows:

x is the independent variable and y is the dependent variable.
3 to fourth power=3^4
3 to ninth power =3^9
Now,
3 to fourth power times to the ninth power=3^4*3^9
the basis same so the powers will add:
3^(4+9)=3^13=1594323
We need to combine like terms, so 4x-3x, and 8y+2y. x+10y is it simplified
Simplified it is 13x-13y+10
