Answer:

Step-by-step explanation:
Given
Shape: Rectangle
Diagonals: AC and BD

Required
Determine BD
From the question, we understand that the shape is a rectangle and its diagonals are AC and BD
Every rectangle has 2 diagonals, both of which are equal.
This implies that:

Recall that:

Hence,

Area = \frac{a X p}{2}
Area = apothem times perimeter over 2
Answer:
Maybe the answer will be C. P ( A and B )
Answer:
C)infinitely many solutions
Step-by-step explanation:

Combine like-terms
-2.1x and 4.9x = 2.8x
3.7 and 5 = 8.7
2.8x + 8.7 is your final answer.
