x =(-2-√-12)/8=(-1-i√ 3 )/4= -0.2500-0.4330i
x =(-2+√-12)/8=(-1+i√ 3 )/4= -0.2500+0.4330i
x = 1/2 = 0.500
54.8. Hope that helped :)
C. because 2.25 X 3 = 6.75 and 6.75 X 3 is 20.25
I think 4 is 3 pages plus 1/4=3 1/4
and 6 is 5+1/3= 5 1/3
hope this helpa
Cos x = 15÷17
because cos is adjacent side over hypotenuse.
