Answer:

x = 25

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

The given is a right triangle

which means one of the angle has a measure of 90

so if we add up all the angles

65 + 90 + x = 180 add like terms

155 +x = 180 subtract 155 from both sides

x = 25

What is the solution to the following equation? x2 + 3x + 4 = 0

andreev551 [17]

Answer:

$x=\dfrac{-3\pm \sqrt7i}{2}$

Step-by-step explanation:

The given equation is $x^{2}+3x+4=0$ .

We need to find the solution of the above equation.

The solution of an equation $ax^2+bx+c=0$ is :

$x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}$

We have, a = 1, b = 3 and c = 4

$x=\dfrac{-3+ \sqrt{(3)^2-4(1)(4)} }{2}, \dfrac{-3- \sqrt{(3)^2-4(1)(4)} }{2}\\\\=\dfrac{-3+\sqrt{9-16}}{2}, \dfrac{-3-\sqrt{9-16}}{2}\\\\=\dfrac{-3\pm \sqrt7i}{2}$

So, the solution of the given equation is $\dfrac{-3\pm \sqrt7i}{2}$ .

How does the multiplicity of a zero affect the graph of the polynomial function?

enot [183]

Answer:

The multiplicity of a root affects the shape of graph of a polynomial. If a root of a polynomial has odd multiplicity, the graph will cross the x-axis at the root. If a root of a polynomial has even multiplicity, the graph will touch the x-axis at the root but will not cross the x-axis

Step-by-step explanation:

Tbh I don't know the answer I just hope this helps

What is two more than 4 times a number is -18 translated and solved

Brrunno [24]

Answer:

n=-5

Step-by-step explanation:

Let "n" represent the unknown number.

So, the equation asks for 4n and two more, or +2, that is all equal to -18.

So, your equation will be:

$4n+2=-18$

First, subtract 2 from both sides:

$4n+2-2=-18-2\\4n=-20$

Then, divide both sides by 4:

$\frac{4n}{4}=\frac{-20}{4}\\n=-5$

Therefore, n=-5.
