7 0

Step-by-step explanation:

{x}^{2}  + 2x - 2 = 0

Now Adding three on both sides we get

{x}^{2}  + 2x - 2 + 3 = 0 + 3

{x}^{2}  + 2x + 1 = 3

{(x + 1)}^{2}   = 3

ehidna [41]

Answer:

720 apples

Step-by-step explanation:

Let A be the number of apples in the small pack.

QTY for Small Cartons is 15A,

QTY for Big Cartons is 20(A+15) = 20A+300

From small cartons makes 25% or 1/4 of total, means the big carton makes 75% of total, or 3/4 of total. This also means the qty in big carton is 3 times of small carton

20A+300 = 3X (15A)= 45A

300 = 25A

A=12

Altogether = 15A+(20A+300) = 720 Apples
