Ok done. Thank to me :>
Answer:
1.90
Step-by-step explanation:
1,4(0,5x + 4,2y) - 3,5(0,2x - 1,5y)
1,4.0,5x + 1,4.4,2y - 3,5.0,2x + 3,5.1,5y
0,7x + 5,88y - 0,7x + 5,25y
0,7x - 0,7x + 5,88y + 5,25y
11,13y
x^3y^3 + 343
The way the sum of cubes works is by taking the roots of each term and applying the formula.
The sum of cubes is as follows:
a^3 + b^3 = (a + b)(a^2 - ab + b^2)
In this case, we would display it like this:
x^3y^3 + 343 = (xy + 7)(x^2y^2 - 7xy + 49)
