2/3x -1/3 = 2(x+2) *(3/3)
2x -1 = 6(x+2)
2x-1= 6x+12
2x-6x =13
4x=-13
X= -13/4

ehidna [41]

Answer:

15.5 ft²

Step-by-step explanation:

A = \frac{1}{2} pa ( p is the perimeter and a the apothem )

Here side of regular pentagon is 3 ft, thus

perimeter = 5 × 3 = 15, so

A = 0.5 × 15 × 2.06 ≈ 15.5 ft ( to the nearest tenth )
