Combine like terms - in this case, that would be the real and imaginary parts:
(8 - 2i) + (5 + 9i) = (8 + 5) + (-2i + 9i)
… = 13 + 7i
Then <em>a</em> = 13 and <em>b</em> = 7.
Answer:
Although the number 30 can be factored different ways, the result is always has one 2, one 3 and one 5. Every possible factor tree for the number 30 is shown below. The number 30 can be written in prime factorization as 3 x 3 x 5. All of the factors are prime numbers.
Note: On the unit circle, P (x, y) = (cos(t), sint(t))
Terminal point of t = 10pi/3 is <span>( -1/2, -sqrt(3)/2)</span>
You can use SAS since you know one pair of sides are congruent and AC splits them so those must make those sides equal. And since those sides, DC and BC, are congruent, the angles must be as well. You can use numbers to prove the angles of D and B or just use that when 2 sides and an angle are congruent, the 3rd side must be congruent.
1 - ( 1 / x) i dont know what you're trying to get but thats what i think.
