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 dimensions of the outer rectangle are
Width = x + 6x + x = 8x
Length = x + 9x + x = 11x
The area is
A1 = (8x)*(11x) = 88x²
The dimensions of the inner rectangle are
Width = 6x
Length = 9x
The area is
A2 = (6x)*(9x) = 54x²
The shaded area is the difference between the outer and inner rectangles.
Therefore the shaded area is
A = A1 - A2 = 88x² - 54x² = 34x²
Answer: 34x²
