Kayla · Answer 1

5

Step-by-step explanation:

(h + k) (x) = x - 2 + 2x + 1

(h + k) (x) = 3x - 1

(h + k) (2) = 3 (2) - 1

(h + k) (2) = 6 - 1

(h + k) (2) = 5

Step-by-step explanation:

(h + k) (x) = [ (x^2 + 1) + (x - 2) ]

=[ x^2 + x - 1 ]

then for [ (h + k) (2) ] ... substitute x with 2 and then calculate ...,

; (2) ^2 + 2 - 1

; 4 + 2 - 1

(h + k) (2) = 5

K (x) = x - 2h (x) = x2 + 1(h + k) (2) =

K (x) = x - 2

h (x) = x2 + 1

(h + k) (2) =
