Answer:
54 cm
Step-by-step explanation:
Perimeter = TZ + TX + RX + RY + SY + SZ
TZ = 5 cm
TX = 13 cm
RY = 9 cm
RX = TX = 13 cm (tangents drawn from and external point)
SY = RY = 9 cm (tangents drawn from and external point)
SZ = TZ = 5 cm (tangents drawn from and external point)
Plug in the values:
Perimeter = 5 + 13 + 13 + 9 + 9 + 5 = 54 cm
Answer:
1.05(0.85y)

15% off so .85y and a 5% tax so 1.05(.85y)
Answer:
None on the above.
Step-by-step explanation:
Here’s what I got:
1/5^-1.
3+(-4)=-1
5^-4/5^3 = 1/5^-1
