11x-2; SInce you have to add 6x and 5x because they are 'like terms' meaning they share the same variable. You also add the 6 and the -8, which is basically doing 6-8, which equals -2. So, you put these two numbers together to get an expression of 11x-2.
Left triangle has a 90 degree angle so 90 plus 35 equals 125. 180 is the total angles in a triangle so subtract to get A. A = 55. The angle of A also helps for B. 55 is part of 180 (a strait line) so that means B is 125. A and C are the same because the is is 2 strait lines intersecting. C is 55. Now for the right triangle. 55 + 70 is 125. do the same thing as we did for A and you should get 55 for D.
Hope this helps!
Answer:
0.46
Step-by-step explanation:
42.78/m = 93
=> m = 42.78/93
=> m = 0.46

Answer:
![\frac{1+5i}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%2B5i%7D%7B2%7D)
Step-by-step explanation:
We know i×i=i^2 which has value of -1.
We will multiply numerator and denominator by i so the denominator will no longer contain imaginary part(s).
Also multiplying by i/i does not change the value of the fraction because i/i=1.
Numerator × i gives (-5+i)i=-5i+i^2=-5i-1
=-1-5i.
Denominator × i gives (2i)i=2i^2=-2.
So the simplified version of this fraction given is:
![\frac{-1-5i}{-2}=\frac{1+5i}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B-1-5i%7D%7B-2%7D%3D%5Cfrac%7B1%2B5i%7D%7B2%7D)
The last simplification come from me multiplying fraction by -1/-1.
You can factor x^2+6x+8 using the AC method.
Which would be: (x+2)(x+4)
Hope I helped.
