Answer:
-12.5 i think
Step-by-step explanation:
To factor you have to do this:
s^2 + 9s = -20
+ 20 +20
s^2 + 9s + 20 = 0
now you need to numbers that multiplied give you 20
and then those same 2 numbers have to add to 9
5 x 4 = 20
5+ 4 = 9
(x + 4) (x+ 5)
that means that x= -4, and -5
let's recall that there are 16oz in 1 lbs, so then 12lbs is 12*16 = 192oz, plus 5, that makes it 197oz, so then 12lb 5oz is really 197oz.
likewise, 7lb is 7*16 = 112oz, plus 10 that makes it 122oz.
197 - 122 = 75 oz
and 75 oz is just 16+16+16+16+11, 4lbs and 11 oz.
