F(-3)=(-3)2 - 1 / -3 + 4
f(-3)= -6 -1 / -3 + 4
f(-3)= -7/1
f(-3)=-7
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.

Answer:
220 cases
Step-by-step explanation:
Each pallet contains 40 cases of tiles.
The yard has 10 complete pallets.
The total number of cases of tiles is therefore:
40 * 10 = 400 cases
If 180 cases are removed for the customer, then the number of cases of tiles remaining is:
400 - 180 = 220 cases
220 cases of tiles will be remaining.
