The complete equation is x^2 - 4x + (-2) = (-2)^2
<h3>How to complete the equation?</h3>
The equation is given as:
x^2 - 4x + __ = (__)^2
_____________________________
Take the coefficient of x
k = -4
Divide by 2
k/2 = -4/2
k/2 = -2
Square both sides
(k/2)^2 = (-2)^2
_____________________________
Add the result of the above computation to both sides of x^2 - 4x + __ = (__)^2
So, we have:
x^2 - 4x + (-2) = (-2)^2
Hence, the complete equation is x^2 - 4x + (-2) = (-2)^2

So here is how we are going to get the measure of angle 2.
Since given that angle COE measures 55°, we will equate <span>m∠2 = 2x and m∠3 = x+10 with 55. So, 55 = 2x + x + 10
55 = 3x + 10
55-10 = 3x
45 = 3x << divide both sides by 3 and the result is
15 = x
So now that we know x, we can now solve for angle 2.
</span>m∠2 = 2x
m∠2 = 2(15)
m∠2 = 30<span>°
I hope that this is the answer that you are looking for. </span>
Step-by-step explanation:
f(x) = 4x + 5, g(x) = 9x − 4
(f-g)(x) = f(x) -g(x)
=4x+5-9x+4
=-5x+9
=9-5x

Um...weird question, but okay. Last digit would be 1.
3^104=... extremely long number, the last digit of which is 1
