Answer:
145%.
Step-by-step explanation:
Given that the price of an item yesterday was $120, and today, the price rose to $294, in order to find the percentage increase, the following calculation has to be made:
120 = 100
294 = X
((294 x 100) / 120) = X
29,400 / 120 = X
245 = X
245 - 100 = 145
Therefore, the percentage increase of the product was of 145%.

Answer:
1) x³-y³ = (x-y)(x²-xy+y²)
2)x²-y² =(x-y)(x+y)
3)x-y = (x-y)
hcf = (x-y)
lcm = (x-y)(x²-xy+y²)(x+y)= (x³-y³)(x+y)
