X^2 - x - 42 = x^2 - 6x + 7x - 42 = x( x - 6) + 7(x - 6) = (x-6)(x+7);
The correct answer is a.
Hello from MrBillDoesMath!
Answer: 23
Discussion:
We only need to check primes less that the square root of 576, which is about 23.98. As 23 is a prime number, it is the answer to the question.
Another way of looking at this: the primes less than or equal to 23
(23*23 = 529)
2, 3, 5,7,11,13,17,19,23
The greatest prime in the list is 23
Thank you,
MrB
The distance formula is derived from the Pythagorean Theorem because the length of one leg of the triangle will always be the difference of the x<span>-coordinates, and the length of the other leg will always be the difference in the </span>y<span>-coordinates</span>
Correct Answer is
Rectangle.
An isosceles triangle can be obtained from cross section of a cone.
Since the height of the cylinder is much larger than the diameter, the resulting cross sectional area would be a rectangle.
For a square, all four sides must be equal. So a cylinder with equal diameter and height will result in a square.
