15 points! What is the length of AB? Use the distance formula to help you decide.
Accepted Solution
A:
Answer: 34Step-by-step explanation: The scale of factor is 2. Then, you must multiply the coordinates of the endpoints AB by 2 to obtain the coordinates od the enpoints A'B': [tex](0*2,-7(2))=(0-14)[/tex] [tex](8*2,8*2)=(16,16)[/tex] Substitute values into the formula, then you obtain that the length A'B' is: [tex]d=\sqrt{(16-0)^2+(16-(-14))^2}\\d=34[/tex]
