Is algebra hard? and what is it about

It’s only hard if you have a stupid teacher (like mine). algebra is all about solving for an unknown variable(s). for example you might have a problem such as 4 + x = 10, what is the value of x? there are so many more complex problems, that’s just a basic pre algebra one. if you are about to take algebra, you’ll be fine. pay attention in class, and do the homework, and take your time. if you mess up one tiny thing in a problem, you’ll get the wrong answer. be patient and do your work.

D. 10x is the correct answer a and c are the common factor of 30 and 20 but it’s not the greatestonly b and d are the answers since 30x^3 -20x20x only have one x and 30 have 3 xso it can only be d.10xhope this will !
