Perimeter is the distance around a shape. The way you find it is by adding the lengths of every side.

In this case, it is 3+4+5=12 cm

Which system of equations can you use to find the roots of the equation 2x3 + 4x2 – x + 5 = –3x2 + 4x + 9?

Degger [83]

Answer:

$y=2x^3+4x^2-x+5$

$y=-3x^2+4x+9$

Step-by-step explanation:

The given equation is in the form $2x^3+4x^2-x+5=-3x^2+4x+9$

We have to evaluate the correct system of equations which can be used to find the roots of the equation.

We can find the root of the equation by plotting the graph of the equations. In order to graph, we can assume the left and right hand side of the given equation as two separate equations.

Therefore, we have

$y=2x^3+4x^2-x+5$

$y=-3x^2+4x+9$

Now, we plot the graph of these two equations in the same coordinate plane. The intersection point (s) would be the roots of the given equation.

Hence, the system of equation that we can use to find the root of the given equation is

$y=2x^3+4x^2-x+5$

$y=-3x^2+4x+9$

Last option is correct.

Using pythagorean theorem, you can find the hypothesis of one triangle.
2^2+b^2=4^2
4+b^2=16
b^2=14
take the square root and you would get b=3.7
After, you would do the same thing, except use 3 for A.
3^2+x^2=3.7^2
9+x^2=13.69
x^2=4.96
take the square root and get x=2.2
