Step-by-step explanation:

Have I got my answer to this is that I figured out how many fours were on our side was there for four so that equals 16 and then I figured out how many threes or worse that there is for threes which would equal to two sixes and then to six ended up with an equal up to 12 and such as the fours I did 4+4 is eight and then 8+8 is 1216 so the simplest form you can put in it is 16+12 and that’s how they got my answer

Answer:

<h2>The scale factor is 285.7143 ≅ 286.</h2>

Step-by-step explanation:

The square sheet has an area of 100 square meters.

Hence, the width of the sheet is $\sqrt{100} = 10$ meters.

The scale factor is needs to be in such a way, so that the film's wide will be match perfectly with the square sheet. Hence, 35x millimeters = 10 meters = 10000 millimeters .

$x = \frac{10000}{35} = 285.7143$ .
