4m = 12x + 40
8x + 8x + 12x + 40 + 4m = 360
28x + 40 + 12x + 40 = 360
x = 7
m = 12(7) + 40 = 124

Answer:
Option (2)
Step-by-step explanation:
ΔDEF is a dilation image of ΔABC.
Rule for the dilation,
Scale factor = 
= 
= 
= 
Therefore, scale factor by which ΔABC is dilated is .
Option (2) will be the correct option.
Answer:
First one would be D (( A'(-3,-6), B'(-5,-4), C'(0,-4) ))
The second would be D (( A'(-15,8), B'(-4,5), C'(-9,6) )) as well
Answer:
The small triangle has a long leg of 8. The triangle area formula is used to derive this. Now, there can be a ration equation.
10/4 = x/8
x = 20
Now use the formula.
A=1/2bh
A=1/2(10*20)
A=100
Area of DEF is 100 m^2.
