Answer:
k+2 or k=2
Step-by-step explanation:
combine -5 and 7 to get your answer
1) 2m+6 / m² + 7m - 12 + (m+2)/(m+4)
= 2(m+3) / (m+4)(m+3) + (m+2)/(m+4)
= 2/(m+4) + (m+2)/(m+4)
= 2+m+2 / (m+4)
= m+4 / m+4
= 1 [ Option A ]
Answer 2) 3/ (x+4) + 7/ (x-3)
= 3(x-3) + 7(x+4)/ (x² +x - 12)
= 3x-9 + 7x + 28 / (x² +x - 12)
= 10x + 19 / (x² +x - 12) [ Option A ]

Answer:
151 -25 = 126 is a factor of the difference of those cubes
Step-by-step explanation:
The expression can be factored as ...
a^3 -b^3 = (a -b)(a^2 +ab +b^2)
151^3 -25^3 = (151 -25)(151^2 +151·25 +25^2)
= 126(151^2 +151·25 +25^2)
That is, 126 is a factor of the difference of the given cubes. The difference is divisible by 126.

Your calculator tells you 151^3 -25^3 = 126 · 27201.
