Answer:
B Building = 865 feet, A Building = 665 feet.
Step-by-step explanation:
If you divide 1530 by 2 you get 765, if you add 100 to 765, and subtract 100 from 865, there is a 200 feet difference from each of the buildings.
Answer:
(since n is assumed to be a constant when integrating with respect to x)
Step-by-step explanation:
You are integrating with respect to x, but 
has no x-terms. Thus, it is considered a constant. The integral of any constant is equal to the constant multiplied by x.
Example: the integral of 2 is 2x, since the derivative of 2x is 2.
If you were integrating 
with respect to x, it would look like this:
Since...
The integral of 
is:
<em>Note: C is a constant. It can be any number.</em>
Answer: (since n is assumed to be a constant)
Answer:
We know that the area of a square of sidelength L, is:
Area = L^2
In this case, we have:
L = 2cm + x cm
And we know that the area of the square is 7cm, then:
Area = 7cm^2 = (2cm + x cm)^2
7cm^2 = 4cm^2 + 4cm*xcm + (x cm)^2
7cm^2 = 4cm^2 + (4*x)cm^2 + x^2 cm^2
Now we can remove all the "cm^2" and just get the numbers:
7 = 4 + 4*x + x^2
We can subtract 4 in both sides to get
7 - 4 = 4 + 4*x + x^2 - 4
3 = 4*x + x^2
This is what whe wanted to prove.
