Answer:
43100
Step-by-step explanation:
A rectangular one-story house covers an area of 3,700 square feet. The ceilings are 8 feet high. The owners add a second floor to the house. The second floor is 50 feet long and 30 feet wide with ceilings that are 9 feet high. What is the total volume of the interior of the house?
Volume = length x width x height
or volume = area x height
Volume of the one- storey = 3700 x 8 = 29600 square feet
Volume of the second floor = 50 x 30 x 9 = 13500 square feet
volume of interior = 29600 + 13500 = 43100 square feet
1824 the estimate is 1820
Answer:
2x − 9 and x + 6
Step-by-step explanation:
2x² + 3x − 54
Factor using the AC method.
2 × -54 = -108
Factors of -108 that add up to 3 are +12 and -9.
Divide by 2 and reduce: 12/2 = 6/1, -9/2 = -9/2.
Therefore, the factors are x + 6 and 2x − 9.
(k-9)²
=(k-9)(k-9)
=k(k)-9(k)-9(k)-9(-9)
=k²-9k-9k+81
=k²-18k+81. As a result, the product of (k – 9)2 using the perfect square trinomial rule shown on the left is k²-18k+81. Hope it help!
