Part A: Find the GCF of 30 and 54. Show your work. Part B: Using the distributive property, along with the GCF you found in Part B, rewrite 30 + 54 as two factors. One factor is the GCF and the other is the sum of two numbers that do not have a common factor. (Look back at your notes for lessons 3.01 and 3.01a to see examples of these.) Show your work.

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

ensure that you have copied down this problem correctly.   .

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."
