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 }
The equation is a quotient statement, and the equation is 51/3 = k
<h3>How to determine the equation?</h3>
The statement is given as:
51 divided by 3 is k
Represent the word "is" with "="
So, we have:
51 divided by 3 = k
Represent the word "divided" with "/"
So, we have:
51 / 3 = k
Hence, the equation is 51/3 = k

D. 8°
Explanation: A triangle is always 180° and we know of two points is 50° and 80°, the other must be 60, the 60° is cut in half so if it’s 30° the other side must be thirty. DBC Is 30+50
Answer:
See below
Step-by-step explanation:
a% of b
= b * a/100 = ab/100
b% of a
= a * b/100 = ab/100
So they are the same.
