That would be written as (m+n^2)(m-n^2)
We solve for b:
4a + 2b = 10 => 2b = 10 - 4a => b = 5 - 2a
15 cookies burned. 3/4 Is equal to 75% so you want to take 75% of 20. OF always mean multiply, but first we divide by 100 to get it into a decimal so 0.75 X 20 equals 15 (if you punch into calculator) so only 5 cookies are not burned. but the 3/4 that for burnt were the other 15
I think it’s 90% cuz it’s 45/50 therefore 90/100
