8n² + 4n - 16 = -n²
8n² + n² + 4n - 16 = -n² + n²
9n² + 4n - 16 = 0
n = <u>-4 +/- √(4² - 4(9)(-16))</u>
                     2(9)
n = <u>-4 +/- √(16 + 576)</u>
                   18
n = <u>-4 +/- √(592)
</u>              18
n = <u>-4 +/- 24.33</u>
              18
n = -<u>4 + 24.33</u>        n = <u>-4 - 24.33</u>
             18                           18
n = <u>20.33</u>                n = <u>-28.33</u>
         18                            18
n = 1.1294              n = -1.57389

e-lub [12.9K]

The length of the vegetable garden as a function of its length will be given as:

  • y = 3x + 2

The expression of the garden width in terms of the width of the tomato patch is given as:

  • y = x + 5

  • Let the length of the garden be y

  • Let the length of the tomato patch be x

If Melissa wants the length of  the garden to exceed three times the length of the tomato patch by 2 feet, the length of the vegetable garden as a function of its length will be given as:

  • y = 3x + 2

If she also wants the garden's width  to <u>exceed the width of the tomato patch by 5 feet,  t</u>he expression of the garden width in terms of the width of the tomato patch is given as:

  • y = x + 5
