Answer:
Step-by-step explanation:
<u>Given the sequence:</u>
The first term is 10 and the common difference is -5
<u>The recursive formula for the given sequence is:</u>
It would be 7 because a line (altitude) that forms a right angle with the triangle will split the side it’s touching in half. The area is 196 because 14x14 is196
the question is not clear.
See diagram
totalarea=totallengtht times totalwidth=(2a+5) times (2a+7)=4a²+24a+35
minus original aera
which is 5 by 7 which is 35
4a²+24a+35-35=4a²+24a
3rd option I think, can't tell which is which
