Answer:
7w^3/5v
Step-by-step explanation:
42v^3w^4/30v^4w
42 = 6 * 7
30 = 6*5 , factor
6*7v^3w^4/6*5v^4w
6 is common, cancel
7v^3w^4/5v^4w
simplify w^4/w = w^3
v^3/v^4 = 1/v
therefore, 7w^3/5v is the answer
Answer:
not sure but i guess its xy^2
Step-by-step explanation:
Subtract 3 to get:
7k^2-6k=0
Clearly, we can factor out a k to find that:
k(7k-6)=0
If either k or 7k-6 is zero, the whole expression is zero, so our solutions are zero and 6/7.
