For example: Square has dimension a
A = a² and if every dimension is multiplied by k new dimension would be:
A 1 = k² a² = k² A.
Or the area of rhombus: A = d1 * d 2 / 2
New area is: A 1 = k d 1 * k d 2 / 2 = k² A
Answer: If every dimension of two-dimensional figure is multiplied by k, the area is multiplied by k².

You can do this by multiplying
Then converting that into a decimal
Then multiplying that by 150

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
