All of the following are ways to prove triangles congruent except. sss, sas, asa, ssa.

Option (d) is correct.

SSA is  not a ways to prove triangles are congruent.

Step-by-step explanation:

Given : The ways to prove triangles are congruent.

We have to choose which one out of given options are not a ways to prove triangles are congruent.

Consider,

1) SSS - Two triangles are said to be congruent when all the three sides of the given triangles are same.

2) SAS - Two triangles are  said to be congruent when two sides of a triangle are same and angle between them is equal.

3) ASA - Two triangles are said to be congruent when two angles of a triangle are equal and side  is equal.

4) SSA - There is no such congruence conditions.

Hence, SSA is  not a ways to prove triangles are congruent.

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}

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
