X=12sin(60). X=10.3923...X=6rad3
Answer:
let x be the number of roses and y the number of daisies
x+y= 9 ( flowers)
3*x will be the cost of the roses
2*y will be the cost of daisies
then 3x+2y= 25 $ ( the cost of the 9 flowers)
therefore the 2 equations
x+y= 9
3*x+ 2*y= 25
solution of the two equations:
we multiply the 1st equation by 2
2x+ 2y= 18
3x+2*y= 25
2nd equation minus 1st equation we will have:
x= 7 therefore y=2
Step-by-step explanation:
The answer would be 166 square miles
