Answer:
Hope that this is helpful.
Step-by-step explanation:
-3(2x-1)^2+12x^2
= -3[(2x-1)(2x-1)]+12x^2
=-3[2x(2x-1)-1(2x-1)]+12x^2
=-3(4x^2-2x-2x+1)+12x^2
=-3(4x^2-4x+1)+12x^2
=-12x^2+12x-3+12x^2
=(-12x^2+12x^2) +12x-3
=0+12x-3
=12x-3

Step-by-step explanation:
The question is incomplete, as the box plot is not given. A general approach to the question, is as follows:
First, identify the 27 mark on the box plot.
Next, count the number of data less than 27.
Take, for instance, there are 6 dots or marks before 27;
This means that 6 bags contain less than 27 ounces
-2b + 7 > 27.5
- 2b > 27.5 - 7
- 2b > 20.5
b < - 10.25
