If you would like to factor completely 13m^2n^3p + 21mp^2, you can do this using the following steps:
<span>13m^2n^3p + 21mp^2 = mp * (13mn^3 + 21p)
</span>
The correct result would be mp * (13mn^3 + 21p<span>).</span>
Answer:
I assume you want the equation for the line in y=mx+b form, if not, you can just transfer this form to standard or intercept. y=(-3/4)x+2.5
Step-by-step explanation:
Since you have the slope and a point, plug in the points to the equation y=9-3/4)x+b to get 4=(-3/4)(-2)+b and solve.

$360.00*.28= 100.80
<span>Or do a portion </span>
<span>28%/100%=100.8/x </span>
<span>Then cross multiply </span>
<span>10080=28x </span>
<span>x=360</span>
Circumference of a circle - derivation
This page describes how to derive the formula for the circumference of a circle.
Recall that the definition of pi (π) is the circumference c of any circle divided by its diameter d. Put as an equation, pi is defined as
π
=
c
d
Rearranging this to solve for c we get
c
=
π
d
The diameter of a circle is twice its radius, so substituting 2r for d
c
=
2
π
r
If you know the area
Recall that the area of a circle is given by
area
=
π
r
2
Solving this for r
r
2
=
a
π
So
r
=
√
a
π
The circumference c of a circle is
c
=
2
π
r
