Explanation
This is a right triangle, so we can use the Pythagorean theorem:
\(AB^2+AC^2=BC^2\)
\((x+2)^2+(3x+3)^2=(2x+7)^2\)
\(x^2+4x+4+9x^2+18x+9=4x^2+28x+49\)
\(10x^2+22x+13=4x^2+28x+49\)
\(6x^2−6x−36=0\)
\(x^2−x−6=0\)
\((x−3)(x+2)=0\)
\(x=3\) or \(x=−2\)
Since side lengths must be positive, Therefore,
\(x=3\)
Answer: B
