Please help me guys i cant figure it out. im sort of stupid
Your model train has one engine and eight train cars. Find the total number of ways you can arrange the train. (The engine must be first.)

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

add 8+12 to get a simplified answer of 12r-20
