Answer:
x= 5
by inscribing angle properties of geometry
The solutions to the quadratic equations are:
a)
b) x = -8, x = 5.
A quadratic function is given according to the following rule:
The solutions are:
In which:
Item a:
The coefficients are a = 5, b = -6, c = -2, hence:
Item b:
The equation is:
x² + 3x = 40
x² + 3x - 40 = 0.
It can be simplified as follows:
(x - 5)(x + 8) = 0.
Hence the solutions are:

Answer:
The degree is the little number above the x so in this case it would be n.
Step-by-step explanation:
The answer would be the second one, you can immediately cross off the first one and 3rd one, 2 x 200 = 400 - 300 = 100 :)
