I think you've written s along with p^2 by mistake. if so, your answer is 2p^2+8pq-q^2.
Answer:
Step-by-step explanation:
yes they are just a rotated triangle
The answer is 29.4 grams.
How to solve:
1. Convert $15 to quarters. You can do this by multiplying 15 by 4. You use 4 because 4 quarters equal to $1. This will equal to 60 quarters.
2. Multiply both 5.76 and 6.25 by 60 to find the weight of $15 in quarters for today and before 1965.
Today: 5.76 g x 60 = 345.6 grams
Before 1965: 6.25 g x 60 = 375 grams
3. Now that you have the weight of quarters for both time periods, subtract! 375 grams - 345.6 grams = 29.4 grams
N=number
n+12 is the expression
43%
there is 100 squares 43 of them are shaded this would be 43/100 or as a percentage it would be 43
