Write an algebraic expression for the given quantity. let x represent the unknown value. one-eight of the sum of a number and three. the algebraic expression for the given quantity is

Required expression for one-eight of the sum of a number and three is

Solution:

Given that unknown value is represented by variable x.

Need to create algebraic expression for One-eight of the sum of a number and three.

Let’s first find one eight of the number that is 1/8th of x =

Now on adding three we get  

Hence required expression for one-eight of the sum of a number and three is

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
