Step-by-step explanation:
(13)2−(2x+7)=0
19x2−2x−7=0
9(19x2−2x−7)=9(0)
x2−18x−63=0
(x−21)(x+3)=0

x - 21 = 0 and x + 3 = 0
x = 21 x = -3
Answer:
Step-by-step explanation:
when you are asked for a unit rate it is always something like this
$5 /pound or 2.2 pounds/ kg
We set up the equation like this:
$13.50/3 pounds
So, for this we need to get 3 pounds down to 1 pound. Also, to make the eqaution balance we need to divide $13,50 by 3 too!
So, the unit rate is $4.5/pound or $4.5 per pound.
