Is the open sentence 8 - 4x = 4x true or false when x=0

kvasek [131]

It is not true because if you add in 0 the equation would be 8-4(0)=4(0)

4x0 = 0

so it would be 8-0=0 which doesn't add up.

find the grouping method to factor the polynomial in the box completely. Use the caret symbol (^) to write the exponent; for exa

sineoko [7]

We start with the polynomial

3x^4 + 12x^3 +27x

Now we search for the common term, in this case it is 3x and factor it out:

3x(x^3+4x^2+9)

Notice that x^3+4x^2+9 cannot be factored anymore then the factorization of the polynomial is:

3x(x^3+4x^2+9)

What is the difference of the polynomials?

Vilka [71]

Answer:

$8r^6s^3-5r^5s^4+r^4s^5+5r^3s^6$

Step-by-step explanation:

We want to simplify;

$(8r^6s^3-9r^5s^4+3r^4s^5)-(2r^4s^5-5r^3s^6-4r^5s^4)$

We expand the bracket to obtain;

$8r^6s^3-9r^5s^4+3r^4s^5-2r^4s^5+5r^3s^6+4r^5s^4$

We now group the like terms to obtain;

$8r^6s^3-9r^5s^4+4r^5s^4+3r^4s^5-2r^4s^5+5r^3s^6$

We now simplify to get;

$8r^6s^3-5r^5s^4+r^4s^5+5r^3s^6$

The correct answer is C
