Explanation

Approximate: 67% of 1800 = 1206. 7% of 600 = 42. 38^2 = 1444. Equation: 1206 + x^2 + 42 = 1444. x^2 = 1444 - 1248 = 196. x = 14.

AI explanation

Approximating the values gives the equation 67% of 1800 + (?)^2 + 7% of 600 = (38)^2. Calculating the known parts results in 1206 + (?)^2 + 42 = 1444. Combining the constants leaves (?)^2 = 1444 - 1248, so (?)^2 = 196. Taking the square root gives the result 14.
