-6K+7K=1K or K
-6k + 7k = k
-6k + 7k = k or 7k- 6k = k or Factor out 'k' k(-6 + 7) = k(1) = k
26-7k=6k First, add 7k to get k on one side. 26-7k+7k=6k+7k 26=13k Divide both sides by 13 to get k by itself. 26/13=13k/13 2=k The answer is 2.
1k
-6k+7k = 1k or normally k on its own.
1k
7k + 4 + 4k - 9 - 5k (7k + 4k - 5k) + (4 - 9) 6k + -5 6k - 5
The answer is 13k .
k + 6k - 13 = 177k = 30k = 30/7k = 4.2857
Same as subtracting 6 from 7 = K
To simplify the expression ((7k - 3)(k^2 - 2k + 7)), you need to apply the distributive property (also known as the FOIL method for binomials). Multiplying each term in (7k - 3) by each term in (k^2 - 2k + 7) gives: [ 7k \cdot k^2 - 14k + 49 - 3k^2 + 6k - 21 ] Combining like terms results in: [ (7k^3 - 3k^2 - 8k + 28). ] Thus, the final simplified expression is (7k^3 - 3k^2 - 8k + 28).
