Question

if
`√( * )`is equal to the coordinate of point D in the diagram above, then X is equal to:

Answer 1

11)

The number line is divided into 5 equal intervals. if the fourth segment is 7, then we would find the distance between each segment

The distance between the fourth segment and the first segment is 7 - - 1 = 8

Since we are considering the distance between segment 1 and segment 4, the distance between each segment would be

8/4 = 2

Thus,

point D = 7 + 2 = 9

If

`\begin{gathered} \sqrt[]{x\text{ }}\text{ = D, then} \\ \sqrt[]{x}\text{ = 9} \\ \text{Squaring both sides of the equation, we have} \\ x=9^2 \\ x\text{ = 81} \end{gathered}`

Option E is correct
