P.S..If you have options then it's better................
The pool has a diameter 20 ft so: r = 10 ft.
The pool cover extents 12 inches beyond the edge of the pool.
12 inches = 1 foot
Therefore, the radius of the pool cover is : r = 10 + 1 = 11 ft.
a. The area of the pool cover:
A = r² π = 11² π = 121 π ft²
b. The length of the rope:
l = 2 r π = 2 · 11 π = 22 π ft.
X=$7 | 1 Ticket= x | 1 Ticket = $7
21x-9+6y
combining terms: 4x+17x=21x
Answer:
1
Step-by-step explanation:
