Answer:
72
Step-by-step explanation:
The correct answer is (x+6)(x+7). Great job.
If there are 646,449 people in 68.3 square miles. each square mile area has 9465 people.
4x - 2y = 14
y = 0.5x -1
Get just one variable on one side for both equations.
4x - 2y = 14 ⇒ 4x = 2y + 14 ⇒ 4x - 14 = 2y
y = 0.5x - 1 ⇒ x - 2 = 2y
Use the transitive property and then solve for x.
x-2 = 4x-14
12 = 3x
x = 4
