Answer:
≈ 35 ft²
Step-by-step explanation:
The area (A) of a regular pentagon is
A = × perimeter × apothem
perimeter = 5 × 4.5 = 22.5 ft, thus
A = 0.5 × 22.5 × 3.1 = 34.875 ≈ 35 ft²
Answer:
1. C
2. A (maybe?)
Step-by-step explanation:
A pen is $2. Using substitution, this is how you solve the system of equations
Let a represent the cost of a photo album and let p represent the cost of a pen.
It is very simple you minus 9 from 7. 9-7=2. So Alberto's birthday is on the 2nd.
