Answer: the correct option is
(d) G and O.
Step-by-step explanation: We are given to find the two points that are at a distance of 4 units from point K.
We have
Distance of point J and L point K is given by

Distance of point I and M point K is given by

Distance of point H and N point K is given by

Distance of point G and O point K is given by

Thus, the required point are G and O.
Option (d) is CORRECT.
What you have to do is take the cube root of eight and 1000 and get your answer. The answer would be 2/10.
Difference of two squares:
(a+b)(a-b) = a² - b²
(a-b)(a+b) = a² - b²
The difference of two squares results to a binomial because the middle term cancels each other out.
example:
a = 2 ; b = 3
(2 - 3)(2 + 3) = 2(2+3)-3(2+3) = 4+6-6+9 = 4 + 0 + 9 = 4 + 9
X2 + 4x + 2x + 8
x2 + 6x + 8
Answer: (x + 4)(x + 2)
