Answer:
c = 64
Step-by-step explanation:
Given
x² - 16x + c
To complete the square
add ( half the coefficient of the x- term )² to x² - 16x
x² + 2(- 8)x + 64
= (x - 8)²
Thus
x² - 16x + 64 = (x - 8)² ← a perfect square
with c = 64
You must factoring the number 192, you will get 192=2^6*3, so you have square root(2^6*3)=2^(6/2)*root(3) applying enhancing property.
Solve the exponent and you get =2^3*root(3)= 8*root(3)
The sum of 5 and 12 is 7 if and only if 5 is a negative integer such that
-5 +12 =7.
Integers are whole numbers which are either negatives or positive normally shown using a number line.
6 apartments in 2.5 hours
30 apartments in ? Hours
6/2.5=30/x
6x=(30)(2.5)
x=75/6
x=12.5 hours
