Answer:
width = 18 cm
Step-by-step explanation:
perimeter of rectangle = 2(length + width)
then:
90 = 2(27+w)
90/2 = 27+w
w = width
45 = 27+w
45 - 27 = w
18 = w
Check:
90 = 2(27+18)
90 =2*45 =
A better estimate would be something that is closer to one you had before...
x^3+8x+5-2x^2+3x+12
x^3-2x^2+11x+17 (is your simplified answer)
