a

17x

b

13x+4

c

13x+14

d

13x-4

D

Step-by-step explanation:

We have the expression:

10x-3+3x-1

To simplify this, we can combine like terms. We have 2 terms with variables, 10x and 3x and 2 constants, - 3 and - 1. To combine the like terms, add the 2 terms with variables and the 2 constants.

(10x+3x) + (-3+-1)

13x+-4

13x-4

The correct answer is D: 13x-4

13x - 4

Step-by-step explanation:

10x-3+3x-1

Combine like terms

10x + 3x - 3-1

13x - 4
