Answer in Decimal is 3.09
Area of a rectangle = length x width
Answer:
n³ + 15n² + 56n
Step-by-step explanation:
The formula for the volume of a rectangular prism is V = l × w × h.
We are given the dimensions of this rectangular prism: n, n + 7, n + 8.
We can assume that these are the length, width, and height of the rectangular prism (not in any specific order).
Let's substitute these values into the formula to find the volume of the prism, written as a polynomial in standard form.
- V = l × w × h
- V = (n) × (n + 7) × (n + 8)
- V = (n² + 7n) × (n + 8)
- V = n³ + 8n² + 7n² + 56n
- V = n³ + 15n² + 56n
The volume of the prism is n³ + 15n² + 56n. This is in standard form because the terms are listed in descending power order.
Answer:
A the answer is A
Step-by-step explanation:
break them apart put 18 into 10 and 8 and multiply it by 30 10 x 30 equals 300
30 x 8 equals 240 add them up you get 540 do the same with next one break 15 into 10 and 5 multiply 20 by 5 and you get 100 multiply 20 by 10 and you get 200 add them up and you get 300 now add the final numbers up and you get 840
