Simplify the expression by combining like terms. 5x+2 I believe it is 7x, but just to make sure.

math
Simplify each expression. Your answer should still be in exponential form. Make sure that you combine all numbers with the same base. y^a/y^b

(x3)/(x+5)< 2 i've asked so many ppl, but they all give me different answers :( Well if the expression is less than two, and the abs function is positive, then the ratio is between 0 and 2. Lets look inside the abs function, it can be negative, because

1) An expression that occurs in calculus in given. Reduce the expression to lowest terms. (2x + 5) 4x  2x^2(2) / (2x+5)^2 I have no idea what to do for this. 2) Simplify the expression. Express the answer so that only positive exponents occur. Assume that
