Answer:
x= -2
Step-by-step explanation:
set the two equations equal to each other, and since the x2 cancels out, you're left with 3x+2= 2x, which simplifies to x= -2
Answer:
Step-by-step explanation:
Population density is expressed as the ratio of the total number of people, N living in or occupying an area or space to the total area or space. Therefore
Population density = number of people/area
A) The town of Manchester (population 50,000) has the shape of a rectangle that is 5 miles wide and 7 miles long. The area would be
5 × 7 = 35 square miles
Population density = 50000/35
= 1429 people/square mile
B) The business area has radius of 1 mile. Its area would be
πr² = 3.14 × 1² = 3.14 square miles.
The area where people reside outside the business area is
35 - 3.14 = 31.86 square miles
Population density = 50000/31.86
= 1569 people per square mile

Step-by-step explanation:
hmu if you wanna arrange something
So squares have 4 congruent sides. When you plot the points (0,0) and (0,5) the side length is 5 units. We can then take 5+5+5+5 and know the perimeter is 20 units.
2.25 x 10^-17. Because it's negative you move the decimal to the left. So 2.5 x 10^-8 is .000000025 and 9 x 10^-10 is .0000000009.
