Answer:
Step-by-step explanation:
Given Equation:
x^3- 4x^2 + 2x+ 10 = x^2 - 5x-3
which simplifies to
x^3- 5x^2 + 7x+ 13 = 0
Given one of the roots is x = 3x+2i, the conjugate is therefore x = 3-2i.
The product is real, (x-3+2i)(x-3-2i) = x^2-6x+13
The other root can therefore be obtained by long division
(x^3- 5x^2 + 7x+ 13)/(x^2-6x+13) = x+1, or x=-1
Therefore the three roots are:
{x=3-2i, x=3+2i, x=-1 }
Answer:
3-a
Step-by-step explanation:
-3(-x+a) 7<5 when x=-1 ?

34.7 because 20.2 + 14.5 = 34.7
hope this helps :):)
The pythagorean theorem works for all right triangles. Just make sure it IS a right triangle.
