Plese help quck 19 + 7 =
20 + 4 =
11 + 5 =
34 + 0 =
19 + 1 =
8 + 9 =
6 + 16 =
9 + 8 =
0 + 0 =
1 + 8 =

19 + 7 = 26

20 + 4 = 24

11 + 5 = 16

34 + 0 = 34

19 + 1 = 20

8 + 9 = 17

6 + 16 = 22

9 + 8 = 17

0 + 0 = 0

1 + 8 = 9

Step-by-step explanation:

a. 19+7= 26

b. 20+4= 24

c. 11+5= 16

d. 34+0=34

e. 19+1= 20

f. 8+9= 17

g. 6+16= 22

h. 9+8= 17

i. 0+0= 0

j. 1+8= 9

A calulator would also help. It'll give instant results.

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}
