Need some math help!!! Factor the polynomial by grouping: 12p^3 − 21 p^2 + 28p − 49

Andru [333]

Answer:

$\left(4p-7\right)\left(3p^2+7\right)$

Step-by-step explanation:

$12p^3-21p^2+28p-49$

$\left(12p^3-21p^2\right)+\left(28p-49\right)$

$7\left(4p-7\right)$

$3p^2\left(4p-7\right)$

$7\left(4p-7\right)+3p^2\left(4p-7\right)$

$\left(4p-7\right)\left(3p^2+7\right)$

I need to equation for the radius of a 400m running track I know the answer is 36.5 and I know the formula is =2<img src="https:

miskamm [114]

This formula only applies if the track is circular. If it is, then we write the equation:

2*r*pi=400

Dividing by 2pi, we see that:

r=200/pi

This is approximately 63.66.
