Plz me figure this algebra 1 question out

option (3m-3)(3m-3)

Step-by-step explanation:

Given in the question an expression,

9m² - 18m + 9

Step 1

divide by 9

9(m² - 2m + 1)

Step 2

factors

-1 x -1 = 1

(-1) + (-1) = -2

Step 3

m² -1m -1m + 1

m(m-1) -1(m-1)

9(m-1)(m-1)

9(m -1)²

(3m-3)(3m-3)

(3m-3)²

3²(m-1)²

9(m-1)²

the answer is b

he has now walked a total of what?

if i know what this is maybe i can
