Semmy [17]3 years ago

Answer:

(x-y)\left(y^{2}-4\right) \text { is the product of }-y^{3}+x y^{2}-4 x+4 y

Step-by-step explanation:

\text { Given equation is }-y^{3}+x y^{2}-4 x+4 y

\text { Writing all }^{a} x^{\prime \prime} \text { terms and "y" terms at a place. }

\left(-4 x+x y^{2}\right)+\left(4 y-y^{3}\right)

Now take “x” common in the first term and “y” common in second term then the equation becomes as follows:

x\left(-4+y^{2}\right)-y\left(-4+y^{2}\right)

x\left(y^{2}-4\right)-y\left(y^{2}-4\right)

(x-y)\left(y^{2}-4\right)

\text { The product of the given equation is }(x-y)\left(y^{2}-4\right)

Here is a balanced hanger diagram
suter [353]

Based on the mass of the circle and the triangle, we can find the mass of the square to be<u> 3.33 grams</u>

<h3>Mass of each side of hanger </h3>

Assuming the mass of the square is x, the equation for the first side is:

= (3 x mass of circle) + (2 x mass of triangle) + (6 x mass of square)

= ( 3 x 2) + ( 2 x 4) + ( 6 × x)

= 6 + 8 + 6x

Mass of other side:

=  (2 x mass of circle) + (5 x mass of triangle) + (3 x mass of square)

= ( 2 x 2) + ( 5 x 4) + ( 3 × x)

= 4 + 20 + 3x

<h3>Mass of square </h3>

As both sides are equal, equate both formulas to find x:

6 + 8 + 6x = 4 + 20 + 3x

6x - 3x = 24 - 14

3x = 10

x = 10/3

x = 3.33 grams

In conclusion, each square is 3.33 grams.

OLga [1]

Step-by-step explanation:

Hey there!

f(x) = 7/x

<em>~ Simply keep the "7" in the place where "x" is there.</em>

f(7) =  \frac{7}{7}

Therefore, X= 1.
