Step-by-step explanation:

Step 1: Define

38y + 15y

38 and 15 are coefficients

y is a term

Since they are like terms, they can be combined

Step 2: Add

38 + 15 = 53

53y

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.

7x7=4 so if u carry the 9 it will be 33
