Answer:
Area of a regular pentagon = pa/2, where p = the perimeter and a = the apothem. If you don't know the perimeter, calculate it from the side length: p = 5s, where s is the side length.
Step-by-step explanation:
Volume = length * width * height = lwh (measured in cubic units)
so 2000 cm^3 = lwh
we know that l = 4w so sub that into the equation
2000 = (4w)*w*h
2000 = 4w^2*h
You didn't include the rest of the question so this is as far as i can go.
Answer:
51.575
Step-by-step explanation:
45 is y and 25 is x is you answer ok
Answer: y = -4/3x + 15
3y = 45 - 4x (subtract 4x from both sides)
y = -4/3x + 15 (divide both sides by 3)
