Answer:
Since b^2 -4ac = 256 we have 2 real distinct root roots
Step-by-step explanation:
4x^2+12x=7
We need to subtract 7 to get it in the proper form
4x^2+12x-7=7-7
4x^2+12x-7=0
The discriminant is b^2 -4ac
when the equation is ax^2 +bx+c
so a =4 b=12 and c=-7
(12)^2 - 4(4)(-7)
144 +112
256
If b^2 -4ac > 0 we have 2 real distinct roots
If b^2 -4ac = 0 we have one real root
If b^2 -4ac < 0 we have two complex root
Since b^2 -4ac = 256 we have 2 real distinct root roots
C) g-0.1g
You multiply gx0.1 then subtract that from the price of apple (g).

I hope this helps! I can't really see #3. Sorry. But I got #'s 1 & 2 though!
Answer:
60:150
Step-by-step explanation:
So first you can divide 210 by 7 since it will be spilt into seven parts.
210/7 = 30
So in order to get them into the ratios:
30 x 2 = 60
30 x 5 = 150
So 210 in the ratio of 2:5 would be 60:150
You can check your work by adding 60 + 150 together.
