4ab(2b-3) is the factored form
Answer: -55
Step-by-step explanation: 8/-2 to get -4, then multiply by 4^2 or 16 to get -64, finally add 9 to get -55.
Answer:3
Step-by-step explanation:
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

Step-by-step ex
He shows the formula to find it which is 360/n, where n is the number of sides of the regular polygon. He goes on further to explain the formula by taking an 18-sided regular polygon as example and computes its exterior angle as 360/18, which is 20 degrees
