Answer: 3(9x-2y)
Step-by-step explanation:
Answer:
Step-by-step explanation:
This is an Arithmetic Series with common difference 4 and first term 3
so the nth term an = 3 + (n -1)4
= 4n - 1.
The sum of n terms
= n/2 (a1 + L)
= n/2(3 + 1671)
= 837n.
There are (1671-3) / 4 + 1 = 418 terms in the series,
so the total value of the series is 837*418
= 349,866.

Your answer is D 6.9*1010 because... Q: 2.3*104=239.2 A 2.3*107=246.1 B 2.3*108=248.4 C 6.9*109=752.1 D 6.9*1010=6,969 >>>> Your answer Your answer is D.
First we have to find the missing angle. And we know that sum of the measurement of angles of a triangle is 180.
So we will get

Now we use sine law, which is

Substituting the values, we will get


The formula of area of triangle, for the given triangle is
