You divide the numerator (top number) by the denominator (bottom number) and you should get a decimal now all you have to do is move the decimal point two places the right and you should get your answer
Given:
edge 1 = 3x - 4
edge 2 = x² - 1
edge 3 = 2x² - 15
perimeter if x = 4
edge 1 = 3(4) - 4 = 12 - 4 = 8
edge 2 = 4² - 1 = 16 - 1 = 15
edge 3 = 2(4²) - 15 = 2(16) - 15 = 32 - 15 = 17
Perimeter = 8 + 15 + 17 = 40 feet.
I believe the correct answers from the choices listed above would be the first and the second option. The conversion factors that are to be used to convert from units of km/min to units of m/hr would be 60 min / 1 h and 1000 m / 1 km. Hope this helps.
