13. the organizers of a running race made a poster showing a scale drawing of the race route. the route follows a
rectangular path with a length of 3 km and width of 2 km, and finishes back at the starting line.
the scale of the drawing is 8 in = km.
the race organizers decide to decorate the poster by covering the entire scale drawing of the course with a piece of
ribbon. what is the total length of the ribbon, in feet? round your answer to the nearest tenth of a foot.
race route on poster =

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
