Answer:
2 (real) solutions.
Step-by-step explanation:
A quadratic always has two solutions, whether they are real or complex.
Sometimes the solution is complex, involving complex numbers (2 complex), sometimes they are real and distinct (2 real), and sometimes they are real and coincident (still two real, but they are the same).
In the case of
x^2+3x = 3, or
x² + 3x -3 = 0
we apply the quadratic formula to get
x = (-3 +/- sqrt(3^2+4(1)(3))/2
to give the two solutions
{(sqrt(21)-3)/2, -(sqrt(21)+3)/2,}
both of which are real.
Answer:
Step-by-step explanation:
So we have:
Multiply both sides by 11:
The right side cancels:
Multiply the left:
Thus, the value of q is 33.
79% = 0.79= 79/100
(not sure if this is what you meant?)
Answer:
perpendicular
Step-by-step explanation:
it isn't parallel because the angles aren't the same.

Answer:
x = 27°
Step-by-step explanation:
The supplements of each angle are complementary:
(180 -6x) +(180 -4x) = 90 . . . . . . . . assumes x is in degrees
270 = 10x . . . . . . add 10x-90
27 = x . . . . . . . . . divide by 10
