Answer:4
Step-by-step explanation:
B) -7x-2x= -20-16
-9x= -36
X= -36 /-9
X= 4
X2=16/25=0.64
,x=0.64^1/2
,x=0.8
3
3/5 x 3 = 9/5
9/5 = 1 4/5

Answer:
551
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
= 
( first + last)
The number of terms is
= a + (n - 1)d ← d is the common difference, a is the first term
d = 5 - 2 = 8 - 5 = 3, hence
2 + 3(n - 1) = 56
2 + 3n - 3 = 56
3n - 1 = 56 ⇒ 3n = 57 ⇒ n = 19
= 
( 2 + 56 ) = 19 × 29 = 551
