The answer is C Kay. Got it?
<span>Simplify For Example :Just as I can pull from a square (or second) root anything that I have two copies of, so also I can pull from a fourth root anything I've got four. </span>
Answer:
146
Step-by-step explanation:
Since John works for 9 hours and makes 14 an hour. You multiply 14 by 9 which equals 126. You add 20 from the tips to 126. This makes 146.
no they are not hope i was helpful xD
Answer:
270
Step-by-step explanation:
For any arithmetic sequence
nth term is given by
nth term = a + (n-1)d
where a is first term,
d is common difference
d is given by nth term - (n-1)th term
sum of n terms given by
sum = n/2(2a + (n-1)d)
________________________________________________
Given arithmetic sequence
-2,0,2,4,6,8...
first term a = -2
lets take third term as nth term and second term as (n-1)th term to find common difference d.
d = 2 - 0 = 2
using a = -2 , d = 2, n = 18
thus, sum of first 18 terms = n/2(2a + (n-1)d)
=18/2( 2*(-2) + (18-1) 2)
=9 ( -4 + 34)
=9 ( 30) = 270
Thus, sum of first 18 terms is 270.
