Answer:
1,583
Step-by-step explanation:
4,861 - 3278 = 1,583. All you have to do is subtract each amount of books from both months.
Part A you would use 200-L ( since you have 400 feet total 200 feet would equal length plus width)
Part B 200 - 80 = 120
Part C 200-90 = 110
area = 90 x 110 = 9900 square feet
Answer:
x=12
Step-by-step explanation:
ab=dc so 15=x+3 you subtract 3 from both sides... x=12
