The expression for the length of UV is 4x + 18
Writing an expression
From the question, we are to write an expression for the length UV
From the given information,
XY bisects UV at W
From this, we can infer that
UW = WV
Also,
UW + WV = UV
∴ UW + UW = UV
2UW = UV
But, we have that
UW = 2x + 9
Thus,
2 × (2x + 9) = UV
4x + 18 = UV
UV = 4x + 18
Hence, the expression for the length of UV is 4x + 18
