Answer:
2
Step-by-step explanation:
This is a polynomial of degree 2 and has 2 solutions.
Answer:
A≈3.14cm²
should be the answer, I am not to familiar with solving equations with approximations.
Step-by-step explanation:
formula:
![d=2r](https://tex.z-dn.net/?f=d%3D2r)
≈ 3.14159cm²
It's D. because you add the powers to get the solution. y x y + y x y = y x y x y x y = y^4
-3 yards per play would be the answer. -12 yards / 4 plays =-3 yards per play.
We can use a variable equation to solve this. Let A represent alan's age, B represent bob's age, and C represent Cindy's age. So Bob's age would be Alan's age - 5, or a -5 = B. Then Bob's age would be double Cindy's age, so that means 2 multiplied by Cindy's age = Bob's age, or 2C = B. Your two equations are:
A - 5 = B
2C = B
Also a third equation that helps is A + B + C = 20.
Finally, here are the ages.
Alan = 11 years old
Bob = 6 years old
Cindy = 3 years old.
