Answer:

15. f(x) +g(x) = 7x +2

16. f(x) -g(x) = -3x +8

17. h(x) · g(x) = 35x -21

Step-by-step explanation:

Substitute the function definition for each function expression and simplify.

15. f(x) + g(x) = (2x +5) +(5x -3)

f(x) +g(x) = 7x +2

16. f(x) - g(x) = (2x +5) -(5x -3)

f(x) -g(x) = -3x +8

17. h(x) · g(x) = (7) · (5x -3)

h(x) · g(x) = 35x -21

Step-by-step explanation:

triangle ABC is equal to triangle ADE by HL. you can solve this by setting up a proportion so for the sides its CB/ED=AB/AD. then just plug in the side lengths, cross multiply and youre done

7/13=x/8+x

56+7x=13x

56=6x

56/6=x

28/3=x
