Answer:
(4x+5)/[(x-1)(x-2)]
Step-by-step explanation:
(4x+5)/(x^2-3x+2)
factor out the trinomial x^2-3x+2 first,
find two numbers that when they multiply, you get the third term, which is 2 in this case. And when they add up, you get the second term, which is -3 in this case. x^2-3x+2=(x-1)(x-2)
1.50 x 7 = 10.5
0.85 x 5 = 4.25
10.5 + 4.25 = 14.75
So you can only have 7 roses . I found this out using trial and error and then adding on the correct number of carnations to make it a dozen and to make sure it equaled 14.75 .
Hope this all makes sense .
