Final answer:
In the expression 10hr + 11h + 6r, the constants are h = 0 and r = 6.
Step-by-step explanation:
To find the constants in the expression 10hr + 11h + 6r, we need to examine the coefficients of h and r.
- The coefficient of h is 10 + 11 = 21, so there is no constant term for h.
- The coefficient of r is 6, so the constant for r is 6.
Therefore, the correct constants for the expression are: h = 0 and r = 6.
