Answer:
Step-by-step explanation:
Let the variable be 'x'.
- Sum of 3 and x = x + 3
- 4 times the sum of 3 and x = 4 (x + 3)
Expression : 4 (x + 3)
On expanding ,
4 (x + 3)
= (4*x) + (4*3)
= 4x + 12 ⟶ equivalent expression to the statement .
To solve this problem you must apply the proccedure shown below:
1. You must multiply the coordinates of by the scale factor given in the problem above. Therefore, you have that the coordinates of
are:
2. The midpoint of has the folllowing coordinates:
3. The center of dilation is a fixed point, with coordinates . Therefore, the distance from the center of dilation to the midpoint of
is:
The answer is the option C:
