Acres = 640 * sq miles
acres = 640 * 3.5
acres = 2,240 square miles

Incidentally, here's how that 640 acres per square mile is derived.
1 acre = 43,560 square feet
1 square mile = 5,280^2 =

Answer:
540, 541, 542
Step-by-step explanation:
let the number be n
hence the 3 consecutive numbers may be expressed as:
n , n+1, n+2
it is given that the sum of the 3 numbers is 1623
hence,
n + (n+1) + (n+2) = 1623
n + n + 1 + n + 2 = 1623
3n + 3 = 1623
3n = 1623 -3
3n = 1620
n = 1620 / 3
n = 540
hence the numbers are
540, (540 + 1) , (540 + 2)
or
540, 541, 542
A triangle, because there's only one way you can fold it to match it's equal side.
The x-intercept is the point where the parabola intersects the x-axis
Answer:
m and n are just labels. They don't really mean anything. In this situation m is used as a general label to be summed over, and n is for a specific term in the sum. They're written differently, because that way you can write things like Which is how we come to the second and third equation you list in your post.
