Official Solution
Correct Option:
(1)
Step 1: Represent the point on the X-axis.
A point on the X-axis has coordinates of the form , since its -coordinate is .
Step 2: Use the distance formula.
The distance between two points and is given by:
Let the point on the X-axis be . The distances from to and must be equal. Thus:
Step 3: Simplify the equation.
Simplify both sides:
Square both sides to eliminate the square roots:
Expand both sides:
Simplify:
Cancel from both sides:

Official Solution
Correct Option:
(2)
Since DE is parallel to BC, the BPT states that the ratio of corresponding sides is equal.
Therefore: AD/AB = AE/AC = DE/BC
Substitute the given values: (x + 4) / (x + 4 + x + 3) = (2x - 1) / (2x - 1 + x + 1)
Simplify: (x + 4) / (2x + 7) = (2x - 1) / (3x)
Cross-multiply: 3x(x + 4) = (2x + 7)(2x - 1)
Expand: 3x² + 12x = 4x² + 12x - 7
Solve for x:** 0 = x² - 7 x² = 7 x = √7
So, the correct answer is (2) √7.
