Let x be the number.
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
The answer to the question
Since the rectangles are similar. The ratio of their sides will be the same.
So, we can write:
Therefore, the left side of the bigger rectangle will be 12 units in length.
