8 0

Answer:

Step-by-step explanation:

x³ - 3x² + 2x - 336 = 0

Find one factor of the polynomial

That's

x - 8

because when its value is equated to zero substituted into the polynomial will give you zero

Factorize x - 8 out

We have

(x - 8) ( x² + 5x + 42) = 0

x - 8 = 0

x = 8

x² + 5x + 42 = 0

Since the roots of this quadratic equation are complex and are not real numbers

Hope this helps you

AO^2 = side a^2 - BO^2
AO^2 = 41^2 -40^2
AO^2 = 1,681 -1600
AO^2 = 81
AO = 9

DO^2 = side b^2 -BO^2
DO^2 = 50^2 -40^2
DO^2 = 2,500 -1,600
DO^2 = 900
DO = 30

Diagonal AD = AO + DO = 9 + 30 = 39 inches
