Answer:
4^2 = 2 x (5 + 3) = 2 x 8 = 16
Step by step solved:
Starting with 4^2 = 2 x (----- + 3), we can work backwards to solve for the missing value:
4^2 = 2 x (----- + 3)
4^2 = 2 x (x + 3) (let x represent the missing value)
4^2 = 2x + 6
16 = 2x + 6 (evaluate 4^2 as 16)
10 = 2x
5 = x
Therefore, the missing value is 5, and the completed calculation is:
4^2 = 2 x (5 + 3) = 2 x 8 = 16
