An algebraic expression that represents the weight of this object is ![W=72+3.9m](https://tex.z-dn.net/?f=W%3D72%2B3.9m)
- Let the weight of this object be W.
<u>Given the following data:</u>
- Weight of object = 72 pounds.
- Increment = 3.9 pounds per month.
To write an algebraic expression that represents the weight of this object:
<h3>
How to write an algebraic expression.</h3>
In this exercise, you're required to write an algebraic expression that represents the weight of this object. Thus, we would choose some variables to denote the parameters that were given in this word problem.
Therefore, the algebraic expression would be written as follows:
![W=72+3.9m](https://tex.z-dn.net/?f=W%3D72%2B3.9m)

A proportional dimension will change the perimeter by the factor of itself. And will change the area by the factor of the dilation squared.
Answer:
49 ÷ 66 × 100= x
Step-by-step explanation:
Step 1
The property of a parallelogram is that diagonals of a parallelogram bisect each other and hence have the same midpoint.
This means that the diagonals cut themselves into two equal halves.
Hence, they must have the same mid-points.
Therefore, if we prove that AC and BD have the same midpoint, then ABCD is a parallelogram.
Step 2
Find the midpoint of BD and AC
![\begin{gathered} (\frac{x_2+x_1}{2}),(\frac{y_2+y_1}{2}) \\ BD=(-\frac{1}{2},\frac{9}{2}) \\ AC=(-\frac{1}{2},\frac{9}{2}) \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%28%5Cfrac%7Bx_2%2Bx_1%7D%7B2%7D%29%2C%28%5Cfrac%7By_2%2By_1%7D%7B2%7D%29%20%5C%5C%20BD%3D%28-%5Cfrac%7B1%7D%7B2%7D%2C%5Cfrac%7B9%7D%7B2%7D%29%20%5C%5C%20AC%3D%28-%5Cfrac%7B1%7D%7B2%7D%2C%5Cfrac%7B9%7D%7B2%7D%29%20%5Cend%7Bgathered%7D)
Since they have the same midpoint, the answer will be;
We Prove that AC and BD have the same midpoint which we have done. we know the diagonals of a parallelogram bisect each other; therefore, they have the same midpoint and ABCD is a parallelogram.
