Answer:
<em>66°</em>
Step-by-step explanation:
mJK = ( 6x - 45 )°
mJH = ( x + 20 )°
mJK = mJH
6x - 45 = x + 20
5x = 65
x = 13
mHK = ( x + 20 )° + ( 6x - 45 )°
<em>mHK =</em> 2 × 33° = <em>66 </em>°
The correct answer is the option "B":
B.(-x-6i)(x-6i)
Explanation
You must keep in mind the following:
1. By definition, a complex number has the following form:
a+bi
"a" is the real part and "b" is the imaginary part.
2. i²=-1
3. Then,you have:
(-x-6i)(x-6i)=(-x²+(6i)²)=-x²-36
4. Therefore, the answer is: (-x-6i)(x-6i)

Answer:
5 weeks
Step-by-step explanation:
$ 9 an hr for 30 hrs.....(9 * 30) = $270
they deduct $ 27 from her weekly check
so she clears (270 - 27) = $ 243 per week
she wants to get to $ 1200...
1200 / 243 = 4.94 weeks......we are gonna have to round up to 5 weeks because 4 weeks is just a little short.
