The quotient of (x^4 + 5x^2 – 3x – 15) and a polynomial is (x^2 – 3). What is the polynomial? A) x^7 + 5x^6 - 6x^4 - 30x^3 + 9x + 45

B) x - 5

C) x + 5

D) x^7 + 5x^6 + 6x^4 + 30x^3 + 9x + 45

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.

the answer is d

hope this

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

is there more to this question?
