How do you find the largest prime factor of a number
sleet_krkn [62]
Hey there,

When finding the largest prime factor of a number, basically all you doing is find the divisible of the number. For example:

What are the prime factors of 8?

                                               8
                                              /  \
                                            4    2
                                           / \       \
                                         2   2      2

Hope that helps.

The formula for the perimeter of a rectangle is P=2(l+w). <br><br> Solve for w.
ale4655 [162]

Step-by-step explanation:

Consider the provided equation.

P=2(l+w)P=2(l+w)

We need to solve the equation for I.

Divide both the sides by 2.

{P}{2}=\frac{2(l+w)}{2}2P=22(l+w)

{P}{2}=l+w2P=l+w

Now isolate the variable I.

Subtract w from both side.

\{P}{2}-w=l+w-w2P−w=l+w−w

I{P}{2}-wI=2P−w

The value of the equation for I is I=\frac{P}{2}-wI=2P−w .

Idk but this might help o_o
