Answer:
$65
Step-by-step explanation:
All 12 of the televisions have extended warranties so 12*15= 180
Then subtract 960-180= 780
Now divide 780/12 = $65
I’m thinking your r in the first equation is actually an x.
X + 2(2x -4) =10
X +4x -8 =10
5x = 18
Answer:

Step-by-step explanation:
2x² + 5x + 3 = (x + 1) (2x + 3)
x² + 2x + 1 = (x + 1) (x + 1)
(x + 1) cancels out because there is one in the denominator and the numerator, leaving you with the answer.
Hope this helps!
