Polynomial identities are just equations that are true, but identities are particularly useful for showing the relationship between two apparently unrelated expressions.
Difference of the squares identity:
WX is 2 WY is 9 because each time it moves it’s moving 1 time
Answer:
It was a percentage increase of 15.15%
Step-by-step explanation:
1140 is greater than 990, so it is an increase in scores
Percentage increase = (change in score / first score) x 100
change in score = second score - first score
1140 - 990 = 150
(150 / 990) x 100 = 15.15%
Hello there! Your answer would be: each persons share was $4.46.
Okay, so to solve this divide the total amount by the number of people there. Note that the equation says "Nina and 3 friends" indicating that Nina is one of these people, and there are 3 others, so we have 4 in total.
$17.84 ÷ 4 = $4.46
So, each person paid $4.46. I hope this helped, and have a great rest of your day! :)
