Answer:
5th term: 20
6th term: 23
Step-by-step explanation:
T5=3n+5
T5=3(5)+5
T5=15+5
T5=20.
T6=3n+5
T6=3(6)+5
T6=18+5
T6=23
T5= 20
T6= 23
Answer:
Step-by-step explanation:
Pretend you see a right triangle here. From the lower end of the line go up 5 and you will be on the same horizontal as the upper end of the line. Go over 6 units and you close your triangle. This is a right triangle with legs 5 and 6 units long. We are looking for the hypotenuse of this triangle. Use Pythagorean's Theorem:

25 + 36 = ??² and
61 = ??² so
?? = √61
The new area would be 270
