Subtract the old amount from the new amount: 2.08-1.21=0.87.
Divide the difference by the old amount: .87/1.21=0.719 or .72 or 72% :)
32^2 + x^2 = 38^2
1024 + x^2 = 1444
-1024 -1024
x^2= 420
x=20.493901532
Answer:
3.1
Step-by-step explanation:
Well x^2 is the same as x-squared (I don't know how to type it).
So to start off, you have x-squared-4x-12
Then you just have to combine the x's, and 1x-4x=-3x
so your final answer would be -3x-squared-12
