Answer:

12x⁶+24x⁵-180x⁴/ 30x³+240x²+450x

Step-by-step explanation:

(x-3)(x+5)=x²+2x-15

12x⁴(x²+2x-15)= 12x⁶+24x⁵-180x⁴

(x+3)(x+5)=x²+8x+15

30x(x²+8x+15)= 30x³+240x²+450x

a rectangle plot measure 20ft. by 30ft. A 3-ft.-wide sidewalk surrounds it.Find the area of the sidewalk.
goldenfox [79]
Area of a rectangle = length (l) * width (w)
A = 30ft * 20ft
A = 600 sq ft

Now the width of a sidewalk that surroundeds it = 3 ft
so now the area of the rectangle with sidewalk= 30+3ft * 20+3ft
A = (33*23) ft
A = 759 sg ft

Area of the sidewalk = 759 - 600
A = 159 sq ft
