I hope this helps you
take both of sides paranthesis square
(2a+7b)^2=(11)^2
4a^2+2.4a.7b+49b^2=121
4a^2+49b^2+56.2=121
4a^2+49b^2=9
In a research of investigating the effects of working in crowded versus uncrowded conditions on the job satisfaction of employees in a variety of work setting , working is a depending variable and crowding is an independent variable.
Given aim of the research is to investigate the effects of working in crowded conditions and uncrowded conditions.
We know that depending variable is a variable whose value is dependent on the other variable. Independent variable is a variable whose value does not dependent on the other variables.
In the given question working may be affected negatively in crowded environment means there will be less work in crowded environment and more work in uncrowded environment.
Hence the depending variable in research is working.

Step-by-step explanation:
Step-by-step explanation:
To answer the question you have t the square of the differences.
So this means that (x-3)^2= x^2-9x+9
Next youmultiply 3 on both sides which says…
x^2-9x+9=27
x^2-9x=18
So, x equals
9/2+3/2 square root 17
OR
9/2-3/2 square root 17
(3-6)-p
It says your subtracting 6 from 3 which is (3-6) and it says "then" that's why we put parentheses and then put "-p"
