The length of DE=sqrt((1-4)^2+(4-0)^2)=sqrt(3^2+4^2)=5
In principle, a rhombus has four equal sides, so the perimeter is 4*5=20 (units)
However, to ensure there is no typo, it is advisable to calculate separately the length of each and every side.

Answer:
-16p³ + 48p² - 16p
Explanation:
In order to simplify the given expression, we need to multiplied 8p with (-2p²+6p-2)
8p*(-2p²+6p-2)
we need to distribute 8p over the brackets or parenthesis.
=8p*(-2p²) + 8p*(6p) + 8p*(-2)
= 8*(-2)*p*p² + 8*6p*p + 8*(-2)* p
= -16p³ + 48p² - 16p
We can't simplify it more, so that's the final answer.
I hope it's help.
