Since I can’t see the figure I would have to assume that if they are the same shape and size then, yes they’re congruent.
Answer:
Group the like terms
6x + 3x - x + 9
Work out the x values together and then add the 9
9x - x + 9
8x + 9
your final answer should be about 8x + 9 as it cannot be simplified anymore
Answer:
area = (1/2)|Ax(By-Cy) +Bx(Cy-Ay) +Cx(Ay-By)|
= (1/2)|2(3-6) +3(6-1) +1(1-3)| = (1/2)|-6 +15 -2|
area = 7/2

Answer:
Part A = D
Part B = 5 and 50
Step-by-step explanation:
Part A:
area = 5*4x = 20x
so, 
Part B:
to leave it only by x, you divide both sides by 20
100/20 = 5, 1000/20 = 50
which
