Hello there! :)

Answer:

x=7

*The answer must have a positive sign.*

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, you expand.

$5(x-3)=5x-15$

$5x-15=x+13$

Then, you add by 15 from both sides of an equation.

$5x-15+15=x+13+15$

Simplify.

$5x=x+28$

You subtract by x from both sides of an equation.

$5x-x=x+28-x$

Simplify by equation.

$4x=28$

Then, you divide by 4 from both sides of an equation.

$\frac{4x}{4}=\frac{28}{4}$

Finally, divide by the numbers from left to right.

$28/4=7$

Final answer is x=7

Hope this helps!

Thanks!

Have a nice day! :)

Define the concept of an angle and show how it should be indicated in Math (notation). Mention at least two ways.

Vedmedyk [2.9K]

An angle is denoted by the angle symbol ∠ and the three letters representing the name of the angle.

An angle is denoted by the angle symbol ∠ which is then being followed by three letters that will represent the points that form an angle.

Lets say for example, the expression ∠ABC will mean that “the angle is formed by the points A, B and C”

where the vertex of the angle is at the point B as it is in the middle.

Angles can also be of different types like:

An Acute Angle which means an angle is less than 90 degrees.

A Right Angle which means an angle which is exactly 90 degrees.

An Obtuse Angle which is an angle more than 90 degrees and less than 180 degrees.

A Straight Angle which is an angle that is exactly 180 degrees.

And a Reflex Angle which is an angle greater than 180 degrees and less than 360 degrees.

Therefore, an angle is denoted by the angle symbol ∠ and the three letters representing the name of the angle.

Answer:

The answer is

Step-by-step explanation:

f(x) = 36x^5 − 44x⁴ − 28x³

g(x) = 4x²

To find f(x) / g(x) Divide each term of f(x) by g(x)

That's

$\frac{f(x)}{g(x)} = \frac{ {36x}^{5} - {44x}^{4} - {28x}^{3} }{ {4x}^{2} } \\ \\ = \frac{ {36x}^{5} }{ {4x}^{2} } - \frac{ {44x}^{4} }{ {4x}^{2} } - \frac{ {28x}^{3} }{ {4x}^{2} } \\ \\ = {9x}^{3} - {11x}^{2} - 7x$
