List price of article = $2,150 percentage discount = 18% retail price =

Retail Price = $1763

Step-by-step explanation:

List price of article = $2150

Percentage discount given = 18%

Then value of discount on the list price = 18% of $2150

                                                                 =

                                                                 = $387

Now the retail price of the article = List price - discount given

                                                       = $2150 - $387

                                                       = $1763

Therefore, Retail price of the article will be $1763

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

(a + b) (a^2 - a b + b^2)

b. f(x) = –√x + 3this is the correct answer
