I would be guessing that since the square is 4ft squared I would imagine that it would have 2ft per side. That would mean 24inches per side. 24×4= 96inches.
96 tiles is what she needs. I am a little confused myself, hope this helps
Answer:
3
Step-by-step explanation:
0•0=0
0+3=3
x+y =15
x-y = 3
add the two equations
2x = 18
divide by 2
x = 9
x + y = 15
9 + y =15
subtract 9
y = 9
The two numbers are 6 and 9
2x+3(4x-15)=25
14x-45=25
14x=70
x=5
y=5
(5,5)
