(-7x + 4)(-7x - 4)
= 49x^2 - 28x + 28x - 16
= 49x^2 - 16.
After each cut, by observing the graph, the remaining area is 80% of the previous area.
It is given that
Actual area = 100cm²
<h3>What is the percentage?</h3>
The percentage is the value per hundred.
According to the graph,
Area after the first cut =80cm² (80% of the previous are)
Area after the second cut = 64 cm²(80% of 80)
Area after third cut = 51.2 cm²(80% of 64)
So we can observe that area after each cut is 80% of the previous area.
Therefore, after each cut, the remaining area is 80% of the previous area.

Answer:
7xy + 2x^2t
Step by step explanation:
You just group the like terms and simplify (pay attention to the signs)
5xy + 2xy = 7xy
-1x^2t + 3x^2t = 2x^2t
So the answer is : 7xy + 2x^2t
