Answer:
7(b^2 -2)(b^2 +2)
Step-by-step explanation:
Factoring the common factor 7 from both terms, you get the difference of squares. That can also be factored.
v = 7(b^4 -4) = 7(b^2 -2)(b^2 +2)
The difference b^2-2 will have irrational factors, so does not meet the problem requirements. This is the factorization over integers.
Answer:
Step-by-step explanation:
30 kg - 4.3 kg = 25.7 kg
25.7 kg - 0.4 kg = 25.3 kg
25.3/2.3 = 11
There are 11 student books in the box.
-1/35 because you multiply the 2 denominators and numerators together. -1 times 1 is -1, 7 times 5 is 35. Make that as a fraction to get -1/35.
1759 if you factor all of the multiples then you would end up with that
