First of all, you will need to find the square footage of the field
that is 360*160
57,600
8 pounds of fertilizer covers 1,000 square feet
(I suppose each bag is 8 pounds)
to see how many square feet each bag covers 1,000/8
each bag covers 125 square feet
to see how many bags you need, you divide the square footage of the field by how many square feet each bag covers
57,600 / 125
that is 460.8 pounds of fertilizer
460.8 / 50 is 9.216 bags of fertilizer
Hope this helps :)
2(2x+1)= (2 x 2x) + (2 x 1) = 4x + 2
So times $64.80 by 2.5. You minus 20 from that, so that the RacerZ is $142. You take that $142 and times that by 1.09. You get 154.78. Therefore;
Speedmonster- 64.80
RacerZ- 142
Swiftee-154.78
Hope this helps. :)
Length = width +6
L * (L - 6) = 135
L^2 - 6L = 135
L^2 - 6L -135 = 0
Length = 15
Width = 9
