Answer:
-3
Step-by-step explanation:
every sequence goes down by -3
The explicit formula is a(n) = 15(n – 10)
<u>Solution:</u>
Given, a term a(19) = 135 and common difference d = 15
We have to find the explicit formula.
Now, we know that, a(n) = a + (n – 1)d where a(n) is nth term, a is first term, d is common difference,
So, for a(19)

Now, we know that, an explicit formula is an expression for finding the nth term,
So, in our problem, expression for finding nth term is a + (n – 1)d

Hence, the explicit formula is a(n) = 15(n – 10).
Answer: 70 Degrees
Step-by-step explanation:
65+45=110
180-110=70 degrees
The perimeter is just the sum of all of the outside edges
So, the perimeter is (2*14)+(2*7), or 28+14, or 42
So the perimeter of figure 1, with all of the information that you have given me, is 42 units
Step-by-step explanation:
I think it is B but I may be wrong I don't know
