VZ is a skew segment to WY
Answer:
(4+x)^2
Step-by-step explanation:
Rewrite 16 as 4^2
4^2+8x+x^2
Check the middle term by multiplying 2ab and compare the result with the middle term in the original expression.
2ab=(2)x(4)x(x)
Factor using the perfect square trinomial rule a^2+2ab+b^2=(a+b)^2, where a=4 and b=x
Anwser:
(4+x)^2
Hopefully that is the correct anwser you're looking for!
<span>x^3 - 6x^2 + 13x - 10
We have been given the roots 2+i and 2, so two of the factors in the desired polynomial is
(x - 2) = 0
(x - 2 -i ) = 0
Let's create a third root by negating the sign of the imaginary component to create the complex conjugate of the known complex root.
(x - 2 + i) = 0
Now multiple (x - 2 - i) and (x - 2 + i)
(x - 2 - i)
(x - 2 + i)
x^2 - 2x - xi
-2x +4 +2i
xi -2i - (-1)
x^2 -4x +4 + 1
x^2 -4x + 5
And we've cancelled the imaginary term. Let's multiply this quadratic equation by the remaining factor.
x^2 -4x + 5
x - 2
x^3 - 4x^2 + 5x
-2x^2 +8x -10
= x^3 -6x^2 + 13x - 10
So the desired polynomial is x^3 - 6x^2 + 13x - 10</span>

Answer: -1/2</h3>
Work Shown:
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (1-3)/(3-(-1))
m = (1-3)/(3+1)
m = -2/4
m = -1/2 is the slope
In decimal form, this converts to -0.5, though usually slopes are in fraction form.
