People with the links be annoying these days bro who even Invented them
Rate-
This is rate because it is a fraction.
Factor both equations, you'll get (x-9)(x+1) for the first one and (x+1)(x-1) for the second one.
new equation: (x-9)(x+1) over (x+1)(x-1). You can cancel out both (x+1)s because when divided by each other you're left with the number one. The answer is (x-9) over (x-10
We can put 0, 1 and 2 for x then y will be :
0, -4 and -8
good luck
You know that each side = 12 in so 8 + 4 = 12 I think not sure
