a builder is designing a rectangular parking lot he has 400 feet of fencing to enclose the parking lot around three sides let x = the width of the parking lot let A = the area of the parking lot the function A(X) = - 2x2 + 400x represents the area of the parking lot as a function of width

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?
