Answer:
27
Step-by-step explanation:
green is 30%
blue is 50%
red is 6 marbles which when calculated is equal to 20%
blue would then be 15 marbles as the whole 100% would equal to 30 marbles
if 40% is added which is also 12 marbles then 15+12 = 27
sin(8x) cos(3x) - cos(8x) sin(3x)
sin(8x - 3x) = sin(5x)

Answer:
Width = 12 cm
Length = 14 cm
Step-by-step explanation:
Rectangle:
Let the width = x cm
So, the length = (x+2) cm
Perimeter = 52 cm
2 *(l+b) = 52
2 *(x+2 + x) = 52
2 * ( 2x + 2) = 52
2x + 2 = 52/ 2
2x + 2 = 26
2x = 26- 2
2x = 24
x = 24/2
x = 12
Width = 12 cm
Length = 14 cm
