The answer to the question is y=<span><span><span>−<span>x2</span></span>+<span>10x</span></span>−<span>14</span></span>
if we take 2100 to be the 100%, what is 273 off of it in percentage?

for this question you would need to utilize ratios to find the side lengths. For example, set up a ratio between the big triangle with the small triangle to find a side length
Lets try 96
4 x ?= 96
? = 96/4
= 24
So we see that 4 times 24 is close to 97.
