can someone help me with my geometry and help me understand what I'm supposed to be doing? this lesson has trigonometry, so its not fully geometry. and maybe someone can hang out with me?

the eight graders whould be the answer

step-by-step explanation: could you give me 5 stars

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."
