In my opinion it is always easier because a fraction like 5/6 and 1/4 is harder to add or subtract than .123 and .421

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

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

Need help with this one

Anon25 [30]

ANSWER

$y = \frac{10}{3} x - 18$

EXPLANATION

The given line has slope

$m_{1} = - 0.3$

The line that is perpendicular to this line has a slope that is the negative reciprocal of -0.3

$m_2 = \frac{ - 1}{ - 0.3}$

$m_2 = \frac{10}{ 3}$

If the line e passes through (3,-8), then the equation is given by,

$y - - 8 = \frac{10}{3} (x - 3)$

$y = \frac{10}{3} x - 10 - 8$

$y = \frac{10}{3} x - 18$

Why can you multiply unlike terms but not add them?

sammy [17]

When you’re adding unlike terms think of the term as a last name. You could never add two last names because that wouldn’t make sense. But with multiplying you don’t need to worry about the “last name”.

How do you simplify the expression (s+t)3

bonufazy [111]

Answer:

3s + 3t

Step-by-step explanation:

To simplify this expression, all you need to do is distribute the 3, which means you basically multiply whatever is in the parentheses by 3:

(s + t) * 3 =

3s + 3t

And that is the simplified form for this expression.

Hope this helps :)
