An expression is shown below:
2x3y + 18xy - 10x2y - 90y

part a: rewrite the expression so that the gcf is factored completely. part b: rewrite the expression completely factored. show the steps of your work.

part c: if the two middle terms were switched so that the expression became 2x3y - 10x2y + 18xy - 90y, would the factored expression no longer be equivalent to your answer in part b? explain your reasoning.

3=log(n)=2

answer a: product property

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

the photograph is photographer and- in the process- ourselves.

step-by-step explanation:

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
