How do you solve 8n squared+4n-16= -n squared using the quadratic formula?
klemol [59]
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

​The perimeter of a square is 28 feet. What is its area<br> ​in square feet?
ruslelena [56]

Answer:

49 feet squared

Step-by-step explanation:

To find the area of the square, we have to find the dimensions. If the perimeter is 28 feet, and a square has equal sides, 28 ÷ 4 = 7

Because each side of the square is 7 feet, to find the area we multiply 7 x 7.

7 x 7 = 49

I hope that this helps! :)
