Answer:
A. (7n-1) (8n-1)
Step-by-step explanation:
56n^2 -8n-7n+1
56n^2 -8n -7n+1
Factor out 8n from the first group and -1 from the second group
8n (7n-1) -1(7n-1)
Factor out the (7n-1)
(7n-1) (8n-1)
Answer:
Answer: A) 15
A natural number is basically a counting number {1, 2, 3, 4, 5, ...} so any positive whole number. That is why 15 is the answer. Choices B and D are fractional values, so we can rule them out. We can rule out choice C because this value is negative.

Answer:
(y+7)²/364 - (x+8)²/364 = 1
Step-by-step explanation:
This is the standard form of a vertical hyperbola (y-k)²/a² - (x-h)²/b² = 1
so, (y²+14y+?) - (x²+16x+?) = 251
(y²+14+49)-49 - (x²+16x+64)-64 = 251
(y+7)² - (x+8)² = 251 + 49 + 64
(y+7)² - (x+8)² = 364
(y+7)²/364 - (x+8)²/364 = 1
