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

Answer:
48
Step-by-step explanation:
im pretty sure
Answer: 1/8
Step-by-step explanation:
Hypotenuse = √97
One leg = 4
By Pythagoras theorem, second leg² = (√97)² - 4²
= 97 - 16 = 81
So second leg = 9
Area of triangle = 4 x 9 / 2 = 18 sq inch
One sq foot = 144 sq inch
So required fraction = 18/144 = 1/8
