klio [65]4 years ago
8 0

Answer:

52 Sides

Step-by-step explanation:

Octagons have 8 sides so 3 x 8 = 24

Pentagons have 5 sides so 4 x 5 = 20

Trapezoids have 4 sides so 2 x 4 = 8

Add it all up and it equals 52 sides in total

-1.2x + 11.45 = 8.21
kondaur [170]
Hi there!

If you solve for x in this problem you would end up with a result of \boxed{x = 2.7}. To find x you need do the following:

First, subtract 11.45 from both sides:

-1.2x+11.45-11.45=8.21-11.45

-1.2x=-3.24

Next, divide both sides by -1.2:

\frac{-1.2x}{-1.2} = \frac{-3.24}{-1.2}

To get the end result of:

\boxed{x = 2.7}

Which system of equations can be used to find the roots of the equation4x^5-12x^4+6x=5x^3-2x?
goblinko [34]

Answer:

y = 4x^5 - 12x^4 + 6x and

y = 5x^3 - 2x

Step-by-step explanation:

The system of equations that can be used to find the roots of the equation 4x^5-12x^4+6x=5x^3-2x are;

y = 4x^5 - 12x^4 + 6x and

y = 5x^3 - 2x

We simply formulate two equations by splitting the left and the right hand sides of the given equation.

The next step is to graph these two system of equations on the same graph in order to determine the solution(s) to the given original equation.

The roots of the given equation will be given by the points where these two equations will intersect.

The graph of these two equations is as shown in the attachment below;

The roots are thus;

x = 0 and x = 0.813
