Answer:

The correct option is 2.

Step-by-step explanation:

The given expression is

7(x+3)

Distributive property: If a,b and c are three real values, then

a(b+c)=ab+ac

In the given expression a=7, b=x and c=3.

Using distributive property, the given expression can be written as

7(x+3)=7(x)+7(3)

7(x+3)=7x+21

The simplified form of given expression is 7x+21. Therefore the correct option is 2.

Tyrone factored the polynomial completely. What is the value of B? 12x4 30x3 4x2 10x Ax(Bx2 1)(2x 5) 2 3 5 6.
Fantom [35]

On comparing with the equation, the value of B is 3.

The correct option is B.

Given

Tyrone factored the polynomial completely.

\rm 12x^4+30x^3+4x^2+10x

<h3>Factorization;</h3>

Factorization is nothing but writing a number as the product of smaller numbers.

The factors of the polynomial are;

\rm 12x^4+30x^3+4x^2+10x\\\\2x(6x^3+15x^2+2x+5)\\\\2x(3x^2(2x+5)+1(2x+5))\\\\2x(3x^2+1)(2x+5)

On comparing with the equation;

\rm 2x(3x^2+1)(2x+5)=Ax(Bx^2+1)(2x+5)\\\\B=3

Hence, the value of B is 3.

Perform the following division and write the quotient in trigonometric form. Write the magnitude in exact form. Write the argume
Tema [17]
\text{ }\frac{-4\text{ - 2i }}{\text{ 3 + 2i}}

Let's apply the Complex Arithmetic Rule:

\frac{a+bi}{c+di}\:=\:\frac{\left(c-di\right)\left(a+bi\right)}{\left(c-di\right)\left(c+di\right)}\:=\:\frac{\left(ac+bd\right)+\left(bc-ad\right)i}{c^2+d^2}

We have: a = -4, b = -2, c = 3 & d = 2

\frac{\left(-4\cdot \:3+\left(-2\right)\cdot \:2\right)+\left(-2\cdot \:3-\left(-4\right)\cdot \:2\right)i}{3^2+2^2}\frac{(-12\text{ - 4\rparen + \lparen-6 + 8\rparen i}}{9\text{ + 4}}\frac{-16+2i}{13}
