Answer:

Option C is correct

$3x^3-4x^2-10$

Step-by-step explanation:

Like terms are those terms which have same variable to the same power.

Find the difference of the following:

$(3x^3-2x^2+4)-(2x^2+14)$

Remove the parenthesis we get;

$3x^3-2x^2+4-2x^2-14$

Combine like terms;

$3x^3-4x^2-10$

Therefore, the difference of $(3x^3-2x^2+4)-(2x^2+14)$ is, $3x^3-4x^2-10$

You are planning to put a new digital flat t.v on a wall that is 12ft long and 9ft high. the digital t.v has a diagonal of 72 in

Pie

Area of wall = 9 * 12 = 108 ft^2
Width of TV = x
Lenght = 2x
Diagonal of TV = 72 " = 6 ft

x^2+(2x)^2=6^2
x^2+4x^2=36
5x^2=35
x^2=36/5
x=sqrt(36/5)
Width = 2.68 ft.
Length = 2.68 * 5.36 = 14.36 ft^2
Area of wall - area of tv = 108 - 14.36 = 93.64 ft

Your friend claims that when a polynomial function has a leading coeffcient of 1 and the coefficients are all integers , every p

sammy [17]

Using the rational root theorem, it is found that your friend is correct.

<h3>What is the rational root theorem?</h3>

It is a theorem that states that for a polynomial with integer coefficients, with q being the factors of the leading coefficient and p being the factors of the constant, every <u>possible rational root</u> is the format $\frac{p}{q}$ .

In this problem:

The leading coefficient is 1, hence it's only factor is $q = 1$ , thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct.
