Answer:
3 x 10 = 30 man-days per house
Answer:
C
Step-by-step explanation:
The 6 comes from the 24(6*4=24)
The 3 comes from the 12(3*4=12)
The 4 is common
the translation takes the point A ( -1, -1) to (-1+4, 1) = (3, 1)
The refection in y = x 'flips' the points so (3, 1) becomes (1, 3) = A"
Do the same procedure for the other points to get the answer
(you should get B" = (-3, 3) )
