Step-by-step explanation:
When f(x) = f(x - 4), 3x² = 3(x - 4)².
=> x² = (x - 4)², x = -(x - 4), 2x = 4, x = 2.
The x-value is 2.
The area of a square is equal to s^2 where s is the length of one side.
49=s^2.
Root both sides to isolate the variable.
7=s
Final answer: 7 ft
It factorises to -
4(x+6)
