x = 5

Step-by-step explanation:

6*(2x+8) = 108

12x + 48 = 108

x =60/12

x = 5

x = 5 units

Step-by-step explanation:

The area of a rectangle equals length times widths, therefore we can use the information from the question to make the following equation...

108 = (2x + 8)(6)

Now we just solve the equation and get...

108 = (2x + 8)(6)

108 = 12x + 48

12x = 108 - 48

12x = 60

x = 60 / 12

x = 5

Therefore, x = 5 units.

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,

mrb
