Distributive property
12-3x-13 = 0
Combine like terms
-1-3x = 0
-3x = 1
Divide by -3
x = -1/3
As it can be seen in the figure above, the figure A'B'C' is bigger than ABC due to dilation.
If we are to measure the side AB, that would be 3. Also, we have A'B' measured to be 6 units.
The dilation factor is calculated by dividing the lengths of the corresponding sides. In this example that would be,
d = A'B' / AB = 6 / 3 = 2
ANSWER: 2
2/1 = (8x-2)/9
2=(8x-2)/9
18=8x-2
20=8x
x=8/20
x=2/5
Answer:
56
Step-by-step explanation:
4*5=20 20/2=10 10*4= 40
4*4=16
16+40= 56
