Arecipe for one batch of cookies uses 23 cup of oil. edward has 114 cups of oil. does he have enough oil to make 2 batches of cookies?

Yes

Step-by-step explanation:

To find how many batches he can make with 114 cups divide 114 by the amount of oil needed to make 1 batch.

114/23=4.95...

He has enough to make 4 batches of cookies.

X² + 7x + 6 = 0
x = -(7) +/- √((7)² - 4(1)(6))
                     2(1)
x = -7 +/- √(49 - 24)
                  2
x = -7 +/- √(25)
               2
x = -7 +/- 5
            2
x = -7 + 5      x = -7 - 5
          2                   2
x = 2              x = -12
      2                      2
x = 1              x = -6

The solution is equal to {1, -6}.
