What is the solution?

Ilia_Sergeevich [38]

Answer:

A. { $3+7i,3-7i$ }

Step-by-step explanation:

The given equation is $x^2-6x+58=0$

Use the quadratic formula with a=1,b=-6 and c=58

Recall the quadratic formula;

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

We substitute the given values to get;

$x=\frac{--6\pm \sqrt{(-6)^2-4(1)(58)} }{2(1)}$

$x=\frac{6\pm \sqrt{36-232} }{2}$

$x=\frac{6\pm \sqrt{-196} }{2}$

Recall that;

$\sqrt{-1}=i$

$x=\frac{6\pm 14i}{2}$

$x=3\pm 7i$

$x=3+7i$ or $x=3-7i$

What are the solutions for x to the equation (x-3)(x+8)=0

hichkok12 [17]

For this case we have a factored expression, of a second degree equation:

( $(x-3) (x + 8) = 0$

To find the solutions:

$x-3 = 0$

we add 3 to both sides of the equation:

$x=3$

$x+8=0$

We subtract 8 on both sides of the equation:

$x = -8$

Thus, the solutions of the equation are:

$x_ {1} = 3\\x_ {2} = - 8$

Answer:

$x_ {1} = 3\\x_ {2} = - 8$

Find the measure of angle x in the figure.

Ghella [55]

Answer:

x = 125°

Step-by-step explanation:

There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.

Total of angles

= (n - 2)•180°

Put in 7, because there are 7 angles.

= (7 - 2)•180°

= 5•180°

= 900°

So the total of the angles should be 900°. We know all of the angles except one.

900° = 123°+129°+128°+128°+132°+135°+ x

900° = 775° + x

Subtract 775.

125° = x

The missing angle is 125°.

Whats issssssss 4x - 8 = 4x

Elenna [48]

Answer:

no solutions

Step-by-step explanation:

4x - 8 = 4x

Subtract 4x from each side

4x-4x - 8 = 4x-4x

-8 = 0

This is never true, so there are no solutions
