If 9 pounds of fertilizer covers 36 square feet of lawn, how many pounds of fertilizer is needed for 210 square feet? round your answer to one decimal places.

9 pounds of fertilizer covers 36 square feet

x pounds of fertilizer covers 210 square feet

x = (210*9)/36

x = 1890/36

x = 52,5

The answer is: 52,5 pounds of fertilizer is needed for 210 square feet of lawn.

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
