WILL MARK BRAINLIEST ANSWER IF IT'S ACCORDING TO TOPIC
17 lb 5 oz minus 12 lb 10 oz

=  1 lb 11 oz

Step-by-step explanation:

recall that 1 lb = 16 oz

To make subtraction easier, we'll convert  everything to oz.

17 lb 5 oz = (17lb)(16 oz/lb) + 5 oz = 277 oz

12 lb 10 oz = (12lb)(16 oz/lb) + 10 oz = 202 oz

the difference between the two

= 227 oz - 220 oz

= 27 oz

=  1 lb 11 oz

10) (7k+6) (3k^2 +8)

11) (6x+7) (7x^2 - 6)

12) (p+6) (p^2 - 3)
