It's A.
Step-by-step explanation:
Since point C divides in the ratio 1:2, one of the coordinates has to be half of the other coordinate. 3 is half of the coordinate 6, which therefore makes it correct.
Answer:
143x/12
Step-by-step explanation:
AREA =(X²-144X)m²
LENGTH =(X+12)m
THEREFORE, WIDTH =AREA/LENGTH
=(X²-144X/X+12)
OR,(X×X-144X/X+12)m
=(143X/12)m
