The formula for the quadratic formula is x (c in this case) = (-b(+/-)√(b²-4ac))/2a
This is used for an equation in standard quadratic form: ax² + bx + c = 0
1.) Put it in the correct form, if not already in it.
Ex. c² + 6c + 8 = 0
2.) Identify each part of the equation:
a = 1 (the leading coefficient), b = 6 (the coefficient in front of the second variable), c = 8
3.) Plug in each variable answer
c = (-6(+/-)√(6²-4(1)(8))/2(1)
4.) Simplify
c = (-6(+/-)√(36-(4*8))/2
c = (-6(+/-)√(36-32))/2
c = (-6(+/-)√(4))/2
c = (-6(+/-)2)/2
*Here, the equation splits in two. It becomes:
c = (-6+2)/2 AND c = (-6-2)/2
*Simplify again:
c = -4/2 AND c = -8/2
c = -2 AND c = -4
The answers c = -2 and c = -4 would solve the given equation.

80$ because 50 divided by 3 is 16.67 and 80 divided by 5 is 16 so yeah $80
remember that when total value is used a negative number is turned positive so it equals to 282 feet
Here are some options to make deciding easier-
A) you went swimming
B) it is raining
C)you are not swimming
D) it is not raining
I think that the answer would be A because the opposite of it not raining would be it raining and the effect of that is that you will go swimming.
Hope this helps... plz mark Brainliest :)
