Answer:
2nd and 4th on edg
Step-by-step explanation:
3+21pi / 2 +4
3-21pi / 2 -4
Answer: 21cm
Step-by-step explanation:
To find the area of a rectangle you just multiply the length by the width. In this case we have 12(width) x ?(length) = 252. To solve we would just divide the area by the known measurement to find the missing one, so 252/12 =21cm
Its an equation that helps you find the hypotenuse of a right triangle
c= √( a²+b²)

^{2}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Bx%5E%7B2%7D%20%2B%208x%20%2B%2041%5D%28x%20%2B%201%29%5E%7B2%7D)
Step-by-step explanation:
If -4 + 5i is a root of a polynomial, then it's conjugate -4 - 5i will also be a root of the same polynomial.
Therefore, the polynomial has 4 degree, and zeroes are (- 4 + 5i), (- 4 - 5i) and -1 with multiplicity 2.
Hence, the polynomial will be

⇒ ![f(x) = [x^{2} + 8x + (4 - 5i)(4 + 5i)] (x + 1)^{2}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Bx%5E%7B2%7D%20%2B%208x%20%2B%20%284%20-%205i%29%284%20%2B%205i%29%5D%20%28x%20%2B%201%29%5E%7B2%7D)

2+11x+121=x+96 is rearranged as: x^2+11x+121-x-96. => x^2 +10x +25, which is like ax^2+bx+c. So D = b^2-4ac = (10^2-4*1*25) = 0. So the discriminant of the given equation is 0.
