Answer: x=-n/a
Step-by-step explanation:
To solve for x, we want to use our properties to isolate x.
[subtract both sides by y]
[divide both sides by a]

Now, we know that x=-n/a.
Answer:
55.95 ft²
Step-by-step explanation:
Circumference formula: C = 2πr => r = C / (2π)
Area formula: A = πr²
Substituting C / (2π) for r in the above equation, we get:
C 47 ft
A = π( ----------- )² = π ( -------------- )²
2π (2π)
or ...
π(47 ft)² 2209 ft²
A = ---------------------- = -------------------- = 55.95 ft²
4π² 4(3.14159)²
Answer:
330
Step-by-step explanation:
11
C
4
We use formula n! /((n-r)!r!)
11!/((11-4)!4!)
11!/((7!)(4!))
11x10x9x8x7!/(7!)(4!)
11x10x9x8/(4!)
11x10x72/24
11x10x3
330
Therefore number of ways =330
