wanza sold a bag of potatoes for sh.420 and made a profit. if she sold it at sh.320 ,she could have made a loss .Given that the profit is thrice the loss ,how much did she pay for the bag of potatoes​

sh.345

Step-by-step explanation:

The difference between the price selling with profit and price selling at a loss is 420-320 = 100

Profit is thrice the loss says we can take the difference in prices and divide it into 4 parts, x and 3x, representing the loss and thrice the loss, or profit margin.

x + 3x = 100

4x = 100

x = 25

loss would be 25,

profit would be 75

sold at a profit: 420 -75 = sh.345

Does this exercise seem similar to what you're doing in class?

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
