Answer:

The answer to your question is:  x1 = - 7 + 9i      x2 = -7 - 9i

Step-by-step explanation:

                                             x² + 14x = - 130

                                            x² + 14x + (7)² = -130 + (7)²

                                           (x + 7)² = -81

                                            x + 7 = ± √-81

         i² = -1,  then                x + 7 = ±√ 81i²

                                            x + 7 = ± 9i

                          x1 = -7 + 9i                         x2 = -7 - 9i

A number from 1 to 25 is chosen at random what is probability of choosing a factor of 10 , an even number or a 7, a smaller numb
Ahat [919]

Step-by-step explanation: need to find a basis for the solutions to the equation Ax = 0. To do this ... 0 0 0 1 −3. ⎤. ⎦. From this we can read the general solution, x = ⎡. ⎢. ⎢. ⎢. ⎢. ⎣ ... two vectors are clearly not multiples of one another, they also give a basis. So a basis ... 4.4.14 The set B = {1 − t2,t − t2,2 − 2t + t2} is a basis for P2.

How do i find the area and perimeter?
Flura [38]
Calculating the area and the perimeter The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.

Find the length of UC on the attached diagram. Thank you!
ValentinkaMS [17]
<h2>Answer </h2>

The length of UC is 18

<h2>Explanation </h2>

First we are going to find the length of JN; then we are subtracting from it the length of JU plus the length of CN.

We can infer from our picture that JN is 82 + 105, so JN = 187

We can also infer that JU = JH + HU

                                     JU = 22 + 96

                                     JU = 118

We can also infer that CN = 51

Now we can fin the length of UC:

UC=JN-(JU+CN)

UC=187-(118+51)

UC=18

We can conclude that the length of UC is 18.
