AB = X^2(3X +2)
C^2 = (x - 3)^2
AB - C^2 = 3x^3 + 2x^2 - (x^2 - 6x + 9)
= 3x^3 + x^2 + 6x - 9
The answer is B. 16 quarts because 4 quarts= 1 gallon
Answer:
The range in temperature is 62° F
Step-by-step explanation:
The range is simply the difference between the highest and the lowest temperature recordings on that particular month.
We obtain the difference between 80 and 18;
80 - 18 = 62
The range in temperature is thus 62° F
Answer:
D. 160
Step-by-step explanation:
The sum of the sequence 1, 2, 3, 4, ... , n is n(n + 1)/2.
Here, you have the sum of 4(1, 2, 3, 4, ... , n), so the sum is 4[n(n + 1)/2]
In this case, the first term is 0, so the last term is the 8th term of the sequence above, so n = 8
4[n(n + 1)/2)] =
= 4[8(9)/2]
= 4[72/2]
= 4(36)
= 144
The closest answer is D. 160
