Answer:
i would recomend tiger algeabra
Step-by-step explanation:
1. c (multiply by 3 to get 9x - 3y = 15)
2. c (add the new top expression with the bottom one to get 11x = 0) substitute 0 into either equation to get -5)
hope this helps!
You do s•s•s•s if you told me the value of s i could tell you the actual answer
So 90^2+90^2=c^2
8100+8100=c^2
16200=c^2
C= ~127.28
