Let's solve your equation step-by-step.

<span><span><span>2<span>(<span>x+4</span>)</span></span>+4</span>=<span><span>12x</span>−1

</span></span>Step 1: Simplify both sides of the equation.

<span><span><span>2<span>(<span>x+4</span>)</span></span>+4</span>=<span><span>12x</span>−1

</span></span><span>Simplify: (Show steps)

</span><span><span><span>2x</span>+12</span>=<span><span>12x</span>−1

</span></span>Step 2: Subtract 12x from both sides.

<span><span><span><span>2x</span>+12</span>−<span>12x</span></span>=<span><span><span>12x</span>−1</span>−<span>12x

Which expression is a polynomial?<br><br> –13

olasank [31]

Polynomials are <em>algebraic</em> expressions whose <em>standard</em> form is defined below:

$p(x) = \sum \limit_{i=0}^{n} c_{i}\cdot x^{i}$

The expression p(x) = - 13 represents a <em>zeroeth</em> polynomial.

<h3>What is a polynomial?</h3>

Herein we must present what the form of polynomials are. Polynomials are <em>algebraic</em> expressions whose <em>standard</em> form is defined below:

$p(x) = \sum \limit_{i=0}^{n} c_{i}\cdot x^{i}$ (1)

Where:

$c_{i}$ - i-th coefficient
n - Grade
x - Independent variable

An example is the expression p(x) = - 13, <em>real </em>numbers can be define as <em>zeroeth</em> polynomials. In this regard, the example can be seen as:

p(x) = 0 · xⁿ + 0 · xⁿ⁻¹ + ... + 0 · x² + 0 · x - 13

<h3>Remark</h3>

The statement is incomplete. We decided to re-define the statement to what polynomials are.

Solve for x. 9 4 13.5 x+4

Lady_Fox [76]

Answer:

x = 2

Step-by-step explanation:

The parallel lines divide the transversals into proportional segments, that is

$\frac{x+4}{13.5}$ = $\frac{4}{9}$ ( cross- multiply )

9(x + 4) = 54 ( divide both sides by 9 )

x + 4 = 6 ( subtract 4 from both sides )

x = 2
