Answer:
x = 5
Step-by-step explanation:
√(2x − 1) + 2 = x
√(2x − 1) = x − 2
2x − 1 = (x − 2)²
2x − 1 = x² − 4x + 4
0 = x² − 6x + 5
0 = (x − 1) (x − 5)
x = 1 or 5
Check for extraneous solutions.
√(2(1) − 1) + 2 = 1
√(1) + 2 = 1
3 = 1
No solution
√(2(5) − 1) + 2 = 5
√(9) + 2 = 5
5 = 5
x = 5
Answer:
option (2) is correct.

Step-by-step explanation:
Given two similar rectangles and with dimension of sides,
we have to choose the correct proportion for corresponding sides.
Since, the rectangles given are similar rectangles.
So, the corresponding sides are in same proportion in case of similar figures,
So,

Thus, option (2) is correct.
