I used synthetic division on the first one cuz I could and got that D is the answer for that one (#3); the next one I used long division and got C. Learn how to do this because it's a method of factoring and factoring is everywhere...it's just as important as being able to solve equations.
Answer:
sqrt(-3)
Step-by-step explanation:
solve using sqrt( b^2 - 4ac)
substitute values from original equation to find discriminant
Answer:
17.51
Step-by-step explanation:
Notes: Circumference= 2 times pi times r
Diameter is double the radius (2r)
How to solve: You just need to divide 55 feet by pi
2(pi)(r)/( pi) = 55/(pi)
2r = 17.51
diameter = 17.51

Answer: Kavitha is 18 and Lizzy is 27
Step-by-step explanation: 8 years ago, Kavitha was 10 and Lizzy was 19.
10 × 2 = 20
20 - 1 = 19
Kavitha is 9 years younger than Lizzy because 27 - 9 = 18
