Quadratic equation is

WHEN

So, to make this true subtract 7 from each side.
The equation is now
7

- x - 7 = 0
Values for a, b, and c: a = 7, b = -1, c = -7
Plug these variables into the quadratic equation.
Square -1 to get 1 and multiply -4 x 7 x -7 to get 196.

Multiply 2 x -7 to get -14, the denominator, and add 1 to 196.
Since 197 is not a square number, and I don't know if you want to leave it in radical form or not, I will just because it's easier to understand.
Hope this helps!
Well here's my work:
=16(2)+24
=32+24
=56
So 56 seconds.
The soap is dirty it hit the floor
I think the answer is a➗3<=9
The <= is ment to be < with a line underneath it, I just don’t have that symbol.
Btw I hope this is right
