What are the solutions to g(x)=7x^2=567

The solution of the given equation is +9 and -9.

Step-by-step explanation:

Given,

To find the solution of x.

or,

or,

or, x = ± [ square roots has two values so we put ±]

or, x = ±9

x = ±9

Step-by-step explanation:

7x^2=567

Divide each side by 7

7/7x^2=567/7

x^2 =81

Take the square root of each side

sqrt(x^2) = sqrt(81)

x = ±9

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
