length and width of a 3in x 5 in photo are tripled what scale factor is used i put 9 id that right
27
To find the scale factor, we need to compare the new dimensions to the original dimensions.
The original dimensions of the photo are 3 inches by 5 inches.
If the length and width are tripled, the new length would be 3 x 3 = 9 inches, and the new width would be 5 x 3 = 15 inches.
Now, let's calculate the scale factor:
Scale Factor = New dimension / Original dimension
For the length: Scale Factor = 9 inches / 3 inches = 3
For the width: Scale Factor = 15 inches / 5 inches = 3
Since both the length and width have the same scale factor of 3, the correct answer is indeed 3.
