Answer:
Cm
Step-by-step explanation:
The areas are in sq. cm
The first step is to define the system of equations.
Take x and y as the cost of a small box and a large box respectively.
Solve the system.
A small box costs $4 and a large box costs $4 too.
Answer:
Area = 20.52 cm^2 and Perimeter = 28.68 cm.
Step-by-step explanation:
Use Pythagoras theorem to find the base of the triangle.
a^2 = 6^2 - 3^2 = 27
a = sqrt27
b^2 = 9^2 - 3^2 = 72
b = sqrt72
Base = sqrt27 + sqrt72
= 13.68
So Area = 0.5 * 13.68 * 3
= 20.52 cm^2 (answer)
Perimeter = 9 + 6 + 13.68
= 28.68 ( answer).
310y=2y^2+xy. This is the answer
