Answer:
D. 25x² - 20x + 4
Step-by-step explanation:
The formula for the area of a square is: A = s², where s = a side length of the square since all side lengths of a square are equal. In this case, the side length is represented by '5x', so the original area is A = (5x)² = 25x².
Since Kelly is cutting off one inch from each side of square, this will actually take off 2 total inches from each side, making the new side length '5x - 2'. We can now put this expression in for the values of 's' in our formula for area and use distributive property to solve:
A = (5x - 2)² = (5x - 2)(5x - 2)
Distribute using FOIL: 25x² - 10x - 10x +4 or 25x² - 20x + 4
Answer:
ln(3x)-x²/2 + x +c
Step-by-step explanation:
∫(2x-1) ln (3x) dx can be computed with parts. The ln part can be made simpler be derivating, and integrating a polynomial wont hurt us that much.
We can derivate ln(3x) using the chain rule, the derivate of ln(x) is 1/x and the derivate of 3x is 3; therefore
(ln(3x))' = (1/3x)*3 = 1/x
A primitive of (2x-1) is, on the other hand, x²-x
Hence
∫(2x-1) = ln(3x) (x²-x) - ∫(x²-x)/x dx = ln(3x) (x²-x) - ∫(x-1) dx = ln(3x) (x²-x) - (x²/2 - x + k) = ln(3x)-x²/2 + x +c
First Coplanar lines are lines which lie on the same plane. The answer is "No" because points M, N and O may not be in the same plane as P. That's the best I can come up with hope it will answer your question.
By applying the definition of difference, we find that the <em>average daily maximum</em> temperature in Syracuse is 26.55 °C higher than the <em>average daily minimum</em> temperature.
<h3>What is the difference between the average daily maximum temperature and the average daily minimum temperature?</h3>
Herein we must find the difference bewteen the two temperatures, defined as the subtraction of the <em>minimum</em> temperature from the <em>maximum</em> temperature:
x = 21.85 °C - (- 4.7 °C)
x = 26.55 °C
By applying the definition of difference, we find that the <em>average daily maximum</em> temperature in Syracuse is 26.55 °C higher than the <em>average daily minimum</em> temperature.

Answer:
1250
Step-by-step explanation:
30,000/24
divide both sides by 24 to get 1250.
