D. city A is more likely because they have the highest population density just divide the population by number of miles that the city covers and that will show you your density
A linear equation will contain a term in x has the highest degree. For example y = 2x - 5 . A non linear will contain terms with exponents 2 or higher
eg x^2 - 2x - 5 is nonlinear.
Answer:
x = 5 or x = 1
Step-by-step explanation:
x² - 6x + 7 = 0
x² - 6x = -7
x² - 6x + 9 = -7 + 9 1/2 of the x term than square it and add it the both sides.
(x - 3)(x - 3) = 2
( x -3)² = 2
= 
(x - 3) = ± 2
x - 3 = 2 or x - 3 = -2
x = 5 or x = 1
X=6 is the answer for the problem
