Ascale drawing of jimmy's living room is shown below:
a rectangle is shown. the length of the rectangle is labeled as length equal to 6 cm, and the width is labeled as width equal to 4 cm.
if each 2 cm on the scale drawing equals 8 feet, what are the actual dimensions of the room?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
