To find perimeter, multiply all sides of a polygon together is false.
![-|x| > 4\ \ \ \ \ |\text{change the signs}\\\\|x| < -4\ FALSE!!!!](https://tex.z-dn.net/?f=%20-%7Cx%7C%20%3E%204%5C%20%5C%20%5C%20%5C%20%5C%20%7C%5Ctext%7Bchange%20the%20signs%7D%5C%5C%5C%5C%7Cx%7C%20%3C%20-4%5C%20FALSE%21%21%21%21%20)
We know |x| ≥ 0 for all real numbers. Therefore your answer is x ∈ ∅ (no solution).

Step-by-step explanation:
![6.5\ cm\xrightarrow{\ \ \ \ \ \ \ \ }52\ mi\qquad\text{divide both sides by}\ 6.5\\\\\dfrac{6.5}{6.5}\ cm\xrightarrow{\ \ \ \ \ \ \ \ }\dfrac{52}{6.5}\ mi\\\\1cm\xrightarrow{\ \ \ \ \ \ \ \ }8\ mi](https://tex.z-dn.net/?f=6.5%5C%20cm%5Cxrightarrow%7B%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%7D52%5C%20mi%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%7D%5C%206.5%5C%5C%5C%5C%5Cdfrac%7B6.5%7D%7B6.5%7D%5C%20cm%5Cxrightarrow%7B%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%7D%5Cdfrac%7B52%7D%7B6.5%7D%5C%20mi%5C%5C%5C%5C1cm%5Cxrightarrow%7B%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%7D8%5C%20mi)
Usually it is 7%
so. 07 × 2,500 = $175
