Answer:
The answer is c :" Mary should isolate the x term because she can then simplify the remaining expression to solve for x."
Step-by-step explanation:
From the equation as written below,
(x-4)(x-1)= 60
the first step is expansion of the bracket, thus we have,
x2-4x-x+4=3(2)60
which equals
x2-5x+4=3(2)60
then the next step should be to isolate x terms to be on one side of the equation while she continues solving for x,
x2-5x= 3(2)60-4
This is because in such simple equations, x could only be found if all terms of x are isolated in one side of the equation before continuing other processes such as factorization,etc.
Answer:
1. x=20 so 2x=40 3x=60 4x=80
2. I don't know
3. x=42 180-45-93=42
