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

Find the volume to the nearest cm3<br> 20 cm<br> 35 cm<br> 12 cm
riadik2000 [5.3K]
Answer: 10380cm^3

Explanation:

Find the volume of half cylinder:

V = (pi x r^2 x h)/2 (I use pi = 22/7 for simplifying)
V = 22/7 x 6^2/2 x 35
V = 22/7 x 36/2 x 35
V = 22/7 x 35 x 18
V = 22 x 5 x 18
V = 1980cm^3

Find the volume of the rectangle:

V = 20 x 35 x 12
V = 240 x 5 x 7
V = 1200 x 7
V = 8400cm^3

Find the volume of the whole shape:

V = 1980 + 8400
V = 10380cm^3

Pls help me with this question and explain how you got the answer!!!!!
Luba_88 [7]

Answer:

-87

Step-by-step explanation:

So, first to find <em>x</em> you need to subtract 121 from 180. You do this because both the angle which measures 121 degrees and <em>x</em> lie on the same line, and since a line has an angle measure of 180, you do 180-121 to find <em>x</em>. The same thing can be done for <em>y</em>. Since the angle measure of 34 degrees and y lie on the same line you can calculate 180-34 to get <em>y. </em>So, let's do that.

180-121=x

59=x

180-34=y

146=y

Once you've done that you can easily subtract the two and get your answer.

x-y

substitute the answer for the variables and get

59-146

and then your answer is

-87
