The scale factor of the dilation of figure A to figure B is 3/2 based on the given parameters
<h3>What is dilation?</h3>
Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor, where the scale factor does not equal one.
<h3>How to determine the
scale factor of the
dilation of figure A to figure B?</h3>
From the figure, we have the following corresponding sides in figure A and figure B
- Side length on figure A = 8 cm
- Corresponding side length on figure B = 12 cm
The scale factor of the dilation of figure A to figure B is calculated using the following scale factor formula
Scale factor = Figure B / Figure A
Substitute the known values in the above equation
Scale factor = 12/8
Divide 12 by 4 and then divide 8 by 4
Scale factor = 3/2
Based on the given parameters, the scale factor of the dilation of figure A to figure B is 3/2

Answer:
S = 5y + 4
Step-by-step explanation:
f is Sara's father, y is Sara, b is Sara's brother and S is sum
3y = f
b = y + 4
S = f + y + b
= 3y + y + y + 4
= 5y + 4
Hope this helps!
