A pool has a width of 34.5 feet and an area of 755 feet, determine the diagonal. Round to the nearest tenth

40.9 feet

Step-by-step explanation:

Rectangle area = length * width

A = l*w

w = 34.5 ft

A = 755 ft.

find diagonal length.

l = A/w = 755/34.5 = 21.884057  = 151/6.9  ft.

d = root ( w^2 + l^2) =  root (34.5^2  + (151/6.9)^2 )

d = root( 1,190.25  + 478.91195)

d = 40.8553784 ft

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

(3x-8) or (3x+8)
