Find x. find y. answer as soon as possible.

 x = -4°     and    y= 13°    

Step-by-step explanation:

From the given figure , it is shown as

(5y - 9) + (14 - 4x) = 90°

Or, 5y -4x = 90° -5°

Or, 5y -4x = 85°       ......1

And

(8y +42)° = (5y -9 +90)°         Note: Alternate interior angle

Or, 3y = 39°

I.e y =

or, y= 13°

Put the value of y in eq 1

5(13°) -4x = 85°

or, -4x = 20°

so, x = -4°

Hence ,  x = -4°     and    y= 13°    Answer

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,
