Before we solve, let's define what a scale factor is. A scale factor is a certain number that can be multiplied or divided by to get a smaller or bigger image that's similar to the current image.
We have 48 by 36 as our original.
It has been reduced to an 8 by 6.
This means we must divide.
Before we get into any complicated ideas, if any, let's try a simple trick.
Divide 48 by 8 and 36 by 6. This should give us a scale factor if they give us the same quotients.
48 / 8 = 6
36 / 6 = 6
It turns out our scale factor is 1/6 (the same as dividing by 6).
The answer cannot be 1/8 because 36 / 8 doesn't give us 8 as a quotient.
The answer also cannot be 6 because we'd have to mutliply our current sides by 6 to get the new image, which it was the opposite.
By elimination and work shown, A.) 1/6 is the correct answer.
I hope this helps!
This is what i got not sure if it’s right
This is really going to be long.......... by using long division:
x^4 +7x³ -2x² -9x -3
______________________________
x+8 I x^5 +15x^4 +54x³ -25x² -75x -34
x^5 +8x^4
----------------
7x^4 +54x³
7x^4 +56x³
------------------
-2x³ -25x²
-2x³ -16x²
--------------
-9x² -75x
-9x² -72x
--------------
-3x -34
-3x -24
-----------
-10
so the result is (x^4+7x³-2x²-9x-3) and -10/((x+8)
25,460 • 10 = 254,600
you can just move the zero over one spot since 10 has one zero
