Use the distributive property to multiply everything in parantheses:
(11 - 12i)(-4 + 6i) = 0
-44 + 66i + 48i + -72i = 0
Factor out the greatest common factor, 2:
<span>2(-22 + 57i + -36i^2) = 0
</span><span>Factor a trinomial: 
2((-11 + 12i)(2 + -3i)) = 0
</span>Set each subproblem equal to 0:
        -11 + 12i = 0                            2 + -3i = 0
-11 + 12i + 11 = 0 + 11               2 + -3i - 2 = 0 - 2
                 12i = 11                                -3i = -2
                     i = 0.917                              i = 0.667

The 3rd term of an arithinetic progression is-9
padilas [110]

Answer:

-64

Step-by-step explanation:

The computation of the 10th term of the progression is shown below:

The 3rd term is -9

A_n = a + (n - 1)d

-9 = a + (3 - 1)d

-9 = a + 2d

-9 - 2d = a

Now the 7th term is -29

A_n = a + (n - 1)d

-29 = a + (7 - 1)d

-29 = a + 6d

Put the a value to the above equation

-29 = -9 - 2d + 6d

-29 + 9 = 4d

-20 = 4d

d = -5

Now

-9 - 2d = a

-9 - 2(-5) = a

-9 - 10 = a

a = -19

Now finally the 10th term of the progression is

= a + (n - 1)d

= -19 + (10- 1)-5

= -19 -45

= -64

Factor <br> x2−6x+9<br><br><br><br><br> a(x+9)2<br><br> b(x+3)2<br><br> c(x−3)2<br><br> d(x−9)2
NeTakaya

Answer:

C. (x-3)^2

Step-by-step explanation:

x^2-6x+9 is a perfect square meaning that (a-b)^2=a^2-2ab+b^2

x^2-6x+9 --> a=x, b=3

so (a-b)^2=(x-3)^2

Answer:

lexie is correct

Step-by-step explanation:

since -68 feet is closer to 0 that means it is greater. the number that is closer to 0 when it is a negative it will be bigger that the other Ex: -5 and -34, -5 is greater because it is closer to 0.
