2. 5, 10, and 20 are factors of 20 that are not also factors of 12.
M = 4b
m = b + 27
4b = b + 27
4b - b = 27
3b = 27
b = 27/3
b = 9......Brandon is 9
m = 4b
m = 4(9)
m = 36.....Michael is 36
In the shown picture, To find the shaded area we need to find the total area of the square, subtracted by the area of the circle.
the area of the shaded region = the area of the square - the area of the circle
the area of the square = L² = 7² = 49 cm²
the area of the circle = πr² = 3.14 x 3.5² = 38.5 cm²
the area of the shaded region = 49 - 38.5 = 10.5 cm²
