"like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. in other words, terms that are "like" each other
only like terms can be combined. we combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily.
the distance between (7, -6) and (-3, -9) is about 10.44.
plug the points into the formula to solve.
0.1515.. * 100 = 15.
0.1515.. * 1 = 0.
0. * 99 = 15
answer is 15/99.
