Answer:

Nickles: 96 times

Penny:  48 times

Step-by-step explanation:

5+3+8+4 = 20 coins in total

20x = 240

x=12 (chance of a coin being picked)

8 nickles(12) = 96

4 pennies(12) = 48

What is negative 6x squared take away 586 =84x take away 4
olchik [2.2K]

Answer:

This equation has no real roots

Step-by-step explanation:

We want to solve

- 6 {x}^{2}  - 586 = 84x - 4

We group all terms on the left:

- 6 {x}^{2}  - 84x - 586 + 4 = 0

- 6 {x}^{2}  - 84x - 582= 0

Divide through by -6

{x}^{2}  + 14x + 97 = 0

The discriminant is

{14}^{2}  - 4 \times 1 \times 97 =  - 192

This means the given equation has no real solution, since the discriminant is less than 0
