To simplify the expression 7x times x, we first rewrite it mathematically as 7x * x.
According to the rules of algebra, when you multiply variables, you can combine them. In this case, x is being multiplied by itself. So, we can express this as:
7x * x = 7 * x * x = 7 * x2
Thus, the simplified form of 7x times x is 7x2.
