Step-by-step explanation:
Let's follow what the problem asks us:
- "The area of a square with side length x"
this is the formula for area:
since the side length is x, the initial area is:
- Now, "where the side length is decreased by 3":
The side is now , thus the area is:
- "the area is multiplied by 2"
we had the area , when we multiply by 2:

Answer:
x = 5
Step-by-step explanation:
39° + 90° + (7x + 16)° = 180°
39 + 90 = 129
180 - 129 = 51
7x + 16 = 51
7x + 16 - 16 = 51 - 16
7x = 35
7x/7 = 35/7
x = 5
