A refrigerator at a home appliance store cost $540.00. What is the total cost of the refrigerator after a 6% sales tax is applied

572.40

Step-by-step explanation:

First find the tax

540 * .06 = 32.4

Add this to the original cost

540+32.4 =572.40

17   x 256=4352

sorry if this is wrong, i'm new.

step-by-step explanation:

hello from mrbilldoesmath!

answer:

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

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

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

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
