Step-by-step explanation:

It`s already in standard form but anyways the correct answer is 49.08
One of the properties of rhombus is its sides are congruent. Therefore, we will only need to find the length of one side using the distance formula. At line YZ, the distance is

D =

= √13
To get the perimeter, multiply one side to 4. Hence,
the perimeter is 4√13 (C)
Answer:
Step-by-step explanation:
(X²+2x+5)(2x)
= 2x(x²) +2x(2x) + 2x(5)
= 2x³ + 4x² + 10x
