Hello,
(x-4)(x+8)(x-2)(x-5i)(x+5i)
=(x^2+4x-32)(x-2)(x^2+25)
=(x^3+2x^2-40x+64)(x^2+25)
=x^5 +2x^4 -15x^3 +114 x^2-1000x+1600
54 = 27 x 2. Third root of 27 = 3 because 3 x 3 x 3 =2. So you get 3root2
Answer:
x=44
Step-by-step explanation:
Area = Width x Length
Area = 108
Square root of 108 = 10.4
108/ 9 = 12 ...12 is not 12 larger than 9
108/ 6 = 18 ...18 is 12 larger than 6
108 = 6 x 18
Width = 6
Length = 18
