180-110=70
180-(70+59)=180-129=51
Z=51 im p sure
Step-by-step explanation:
We have,
If a quadratic equation with real coefficients has a discriminant of -36.
The general form of quadratic equation is :

The discriminant of this equation is : 
If D=0, it will have 1 real roots
If D>0, it will have 2 real roots
If D<0, it will have no real roots
We have,
D = -36 < 0, so, the quadratic equation will have no real roots.
Hey there!
-4.36 + 1.2 [2.8 +(-3.51)]
= -4.36 + 1.2(2.8 - 3.51)
= 4.36 1.2(-0.71)
= -4.36 - 0.852
= -5.212
Therefore, your answer is: -5.212
Good luck on your assignment and enjoy your day!
