A) 2x(4x-1)=10
Expand
8x^2-2x=10
Divide all terms by 2
4x^2-x=5
4x^2-x-5=0
4x^2+4x-5x-5=0
4x(x+1)-5(x+1)=0
(4x-5)(x+1)=0
x is equal to -1 and 5/4
but, in this case, the side of a rectangle cannot be negative, so the only answer that is mathematically possible is 5/4
b) substitute 5/4 into given expressions
length: 4(5/4)-1 which is 4cm
width: 2*5/4 which is 2.5cm
c) plus all four sides together
2.5+2.5+4+4 which is 13cm

conclusion
Answer:
It really depends on a person. For some, living in order to achieve glory is enough; for others, it is not.
If I'm to talk from my own perspective, it isn't a reasonable motivation in life. You should strive to be happy and satisfied with yourself, learn how to love and appreciate yourself, and if you only want glory and that is the reason why you study and work, I don't think it will make you truly happy when and if you achieve it. Pursuing glory is something trivial when compared to other, more important motivations in life, such as self-accomplishment and genuine happiness and satisfaction. Even when you achieve that desired glory, I believe that feeling is fleeting and that you will want to achieve something else, which makes your initial motivation worthless.
