If 2 is one root of the equation 4x3 + kx - 24 = 0, then the value of k is a) -1
b) -4
c) 8
d) impossible to determine

B

Step-by-step explanation:

We are given the equation:

And that x = 2 is a root. And we want to determine the value of k.

By definition, since x = 2 is a root of the equation, when x = 2, the equation must equal zero:

Solve for k:

Hence, the value of k is -4.

In conclusion, our answer is B.

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
