Solve 2/5(15x-20)=3(3x-4)

1 answer:

3 0

If you would like to solve 2/5 * (15x - 20) = 3 * (3x - 4), you can do this using the following steps:

2/5 * (15x - 20) = 3 * (3x - 4)
6x - 8 = 9x - 12
-8 + 12 = 9x - 6x
4 = 3x
x = 4/3 = 1 1/3

The correct result would be 4/3.

Factor this expression completely, then place the factors in the proper location on the grid.

andreev551 [17]

Notice that you have a difference of cubes:

$\dfrac{x^3}8-\dfrac{y^3}{27}=\left(\dfrac x2\right)^3-\left(\dfrac y3\right)^3$

which can be factored using the rule,

$a^3-b^3=(a-b)(a^2+ab+b^2)$

So,

$\dfrac{x^3}8-\dfrac{y^3}{27}=\left(\dfrac x2-\dfrac y3\right)\left(\dfrac{x^2}4+\dfrac{xy}6+\dfrac{y^2}9\right)$

and just to make things look nicer, we can pull out 1/6 from the first factor and 1/36 from the second to get

$\dfrac{x^3}8-\dfrac{y^3}{27}=\dfrac1{216}(3x-2y)(9x^2+6xy+4y^2)$
