Write three-letter combinations or codes according to this plan: The 1st letter must be "b" or "c".
The 2nd letter must be a vowel.
The 3rd letter must be chosen from "t, v, or x".
How many such words can be written? (These do not have to be English words, or real words of any other
language for that matter.)

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

factor trees are nice.

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
