Fas a function of x is equal to the square root of quantity x plus two; g(x) = 8x - 6 find f(g( f(g(x)) = 8 times the square root of quantity x minus four f(g(x)) = 2 times the square root of quantity two x plus one f(g(x)) = 2 times the square root of quantity two x minus one f(g(x)) =8 times the square root of quantity x plus two minus 6

f(x)=

g(x)=8x-6

f(g(x))=

the third option

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.

wait nvm i know the correct answer now its 100%   81 square feet
