<u>Answer:</u>
The correct answer option is: 19, 13, 3, -11, -29.
<u>Step-by-step explanation:</u>
We are given the following explicit formula for an arithmetic sequence:
![a_n=21-2n^2](https://tex.z-dn.net/?f=a_n%3D21-2n%5E2)
So to find the first five terms of this sequence, we will substitute the values of
(num here in the given formula:
![a_1=21-2(1)^2\\\\a_1=19](https://tex.z-dn.net/?f=a_1%3D21-2%281%29%5E2%5C%5C%5C%5Ca_1%3D19)
![a_2=21-2(2)^2\\\\a_2=13](https://tex.z-dn.net/?f=a_2%3D21-2%282%29%5E2%5C%5C%5C%5Ca_2%3D13)
![a_3=21-2(3)^2\\\\a_3=3](https://tex.z-dn.net/?f=a_3%3D21-2%283%29%5E2%5C%5C%5C%5Ca_3%3D3)
![a_4=21-2(4)^2\\\\a_4=-11](https://tex.z-dn.net/?f=a_4%3D21-2%284%29%5E2%5C%5C%5C%5Ca_4%3D-11)
![a_5=21-2(5)^2\\\\a_5=-29](https://tex.z-dn.net/?f=a_5%3D21-2%285%29%5E2%5C%5C%5C%5Ca_5%3D-29)
Therefore, the first five terms of the sequence defined by the explicit formula
are 19, 13, 3, -11, -29.
The triangles that would be created if the rectangle has a length and width that are different is a right scalene triangle.
It will have one right angle and all three sides of the triangle will be different lengths because the hypotenuse (the diagonal will be longer than the other two sides.
