Can you guys please help me

x^2 - 9

x^2 - 4

Step-by-step explanation:

x+3        x-3

*

x+2       x-2

Notice that the numerator is the difference of squares and the denominator is the difference of squares

(a+b)(a-b) = a^2 - b^2

(x^2 - 3^2)

x^2 - 2^2

x^2 - 9

x^2 - 4

A...

the parts of theis problem are "special factors" or conjugates

(a+b) (a-b) = a^2 - b^2

you have two of those (x+3)(x-3) = x^2-9

and (x+2)(x-2) = x^2 -4

Step-by-step explanation:

The equivalent equation of is .

Step-by-step explanation:

The given equation is

Where d is density, m is mass and V is volume.

We have to solve this equation for V. To separate the variable V on one side multiply both sides by V.

Diven both sides by d.

Therefore the equivalent equation of the given equation is .
