K would be the 180 anti clock and up to
Answer:
-14x + 4y
Step-by-step explanation:
Step 1: Set up expression
(-10x - y) - (4x - 5y)
Step 2: Distribute negative
-10x - y - 4x + 5y
Step 3: Combine like terms
-14x + 4y
2nd is good no cap about it
Number: n
square of number: n^2
sum of n and n^2 is n+n^2=20
Rewriting this equation, we get n^2+n-20=0 = (n+5)(n-4) = 0
Then n+5=0 and n-4=0, so n = -5 and n = 4.
You must check both results. It could happen that both are correct, or that only one is correct.
Is the second one
x^2+(y-2)^2=25
