Please solve the image attached

A = 50x - 25

Step-by-step explanation:

The area (A) of the rectangle is calculated as

A = length × width

   = 4 (12x - 6) ← change mixed number to improper fraction

  = (12x - 6) ← multiply each term in the parenthesis by

   = 50x - 25

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

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,
