Answer:
square root of 25=5 and square root of (x+9)=(x+9) so the answer is.... x+9=+-5
Step-by-step explanation:
Answer:
12,434
Step-by-step explanation:
since after the decimal point the number ranges 0-4 it will nullify but if 5-9 it will add 1 to the number before the point
560+ 147= 707
14(40)= 560
14+ 14(1/2)=21
21(7)= 147
The nth term is
an=a1(r)^(n-1)
an=1(2)^(n-1)
a1=1
r=2
the sum of a geometric seequence is

a1=1
r=2
we want to find

(since we minus 1, the highest exponet is 9 so add 1 to make it correct)
