3t=4s+5 (s=side of square, t= side of triangle)
s=t-3, t=s+3, using this value for t in the first equation gives us:
3(s+3)=4s+5
3s+9=4s+5
-s=-4
s=4
so the side length of the square is 4cm and the area of a square is just s^2
A=16cm^2

Answer:
A) 96 + x ≤ 149
Step-by-step explanation:
The airplane can hold 149 passengers.
There are already 96 passengers on board.
They can add x additional passengers, as long as they bring the total to no more than 149.
The inequality is
96 + x ≤ 149
