Here, Equation: 2x + 3 > 10
Subtract 3 from the both sides,
2x +3 - 3 > 10 - 3
2x > 7
Now, divide by 2,
2x/2 > 7/2
x > 7/2
In short, Your Answer would be: x > 7/2 or x > 3.5
Hope this helps!

Let the length of square be l(length)
Perimeter of square = 4l
48cm= 4l
48/4= l
12=l
This,l=12 cm
To find the sum of the interior angles you use the formula (n-2)(180), where n is the number of sides. In this case, the number of sides is 12, so you get 1800 degrees. Then you divide by number of angles which is 12. So your answer is 150 degrees.
