X = 7 / sin(45)
x = 7 / sqrt(2)/2
x = 7 sqrt(2)
It is positive 6x. Hope this helps!
Answer:
4+3i
Step-by-step explanation:
the 
needs to be simplified
first, I broke it down to
and 
simplifies to i ;and can be broken down to 
and
can be simplified further to 3
Now all you have to do is put it together
4(which you didnt have to do anything to)+ 3i( 3 from the sqrt of 9 and i from the sqrt of -1) sqrt 3( which cant be simplified further)
To figure this out i would just dived 2.8 by 3 then multiply by two. I do not know if you must keep it as a fraction but this is the easiest way for me to do it
false becasue 11,12,13,14,15,16,17,18,19,20,21, and 22 is bigger and 111,112,113,114,115,116,117,118,119,120,121, and 122 is smaller.
