Suppose that the functions f and g are defined for all real numbers x as follows. f(x)=x+5
g(x) = 4x+1
Write the expressions for (fg)(x) and (f+g)(x) and evaluate (f-g)(1).
(9)(x) = |
(r + g)(x) = 0

step-by-step explanation:

3 is greater then both of those numbers

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.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
