Step-by-step explanation:
1a. Just add both of them.
[tex]8x - 3 + 4x + 5 = 12x + 2[/tex]
1b. We just subtract both of the functions.
[tex](8x - 3) - (4x + 5) = [/tex]
[tex]4x - 8[/tex]
1c.
[tex](8x - 3)(4x + 5)[/tex]
[tex]32 {x}^{2} + 28x - 15[/tex]
1d.
[tex] \frac{8x - 3}{4x + 5} = 2 - \frac{13}{4x + 5} [/tex]
