Letter D will be your answer. So, the answer is f(x)-4.
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:
9 cups
Step-by-step explanation:
1 m³ = 10⁶ ml
0.21×0.05×0.3 = 0.00315 m³ × 10⁶
= 3150 ml
No. of cups: 3150 ÷ 350 = 9
Area of base = 1/2 x 4 x 3.5 = 7 m²
Perimeter of the base = 4 + 4 + 4 = 12 m
Surface area = 7 + 7 + 12 x 11 = 146 m²
Answer: 146 m²
If she wants an average of 73 for 3 tests,
she needs a total of 73 x 3 = 219
Total of the first 2 tests = 77 + 75 = 152
Scores needed for her 3rd test = 219 - 152 = 67.
Answer: She needs a score of 67 marks.
