Answer:

x = 16.8

Step-by-step explanation:

The ratio of corresponding sides is equivalent to the ratio of the perimeters.

Then using proportion

\frac{12}{x} = \frac{5}{7} ( cross- multiply )

5x = 84 ( divide both sides by 5 )

x = 16.8

Answer:

8.38

Step-by-step explanation:

The underlined number is in the hundredths place, so that means that we're going to round there. That means that you look at the number to its right and if it's lower than 5, it stays the same. However, if it's 5 or higher, you round it up. For example, if the number was 8.386, we would round it to 8.39.
