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
I’m not sure bc i did this years ago but u might want to go to ur teacher for some help
Answer:
Step-by-step explanation:
The third one
Answer:
2 and -5
Step-by-step explanation:
