X -

x + 4 = -

First, simplify

to

/ Your problem should look like: x -

+ 4 = -
Second, simplify x -

+ 4 to

+ 4 / Your problem should look like:

+ 4 =
Third, regroup terms. / Your problem should look like: 4 -

= -
Fourth, multiply both sides by 2. / Your problem should look like: 8 - x = -1
Fifth, subtract 8 from both sides. / Your problem should look like: -x = -1 - 8
Sixth, simplify -1 - 8 to -9. / Your problem should look like: -x = -9
Seventh, multiply both sides by -1. / Your problem should look like: x = 9

Answer:
24π cm
Step-by-step explanation:
s = (∅/360) * 2πr
s = (216/360) * 2π(20)
s = (216/360) * 2 * 20 * π
s = 24π cm
