7

Step-by-step explanation:

if the total is 49 squared, and squared means a number times itself, then the answer would be whatever number times itself is 49, will be the answer in this case, its 7

Ex: 9 squared=3x3

Step-by-step explanation:

Solving each equation

x + 6 = 2 ( subtract 6 from both sides )

x = - 4 ≠ 8

x + 2 = 10 ( subtract 2 from each side )

x = 8 ← True

x - 4 = 4 ( add 4 to both sides )

x = 8 ← True

x - 2 = 10 ( add 2 to both sides )

x = 12 ≠ 8

2x = 4 ( divide both sides by 2 )

x = 2 ≠ 8

3x = 24 ( divide both sides by 3 )

x = 8 ← True

The equations where x is a solution are

x + 2 = 10 , x - 4 = 4 and 3x = 24
