Answer:
x²-9=x²-3²=(x+3)(x-3)
Step-by-step explanation:
use formula
a²-b²=(a+b)(a-b)
$96(2 payments) = $192
$192/(12 months) = $16 per month (she should set aside)
Answer:
Slope
Step-by-step explanation:
The point of slope is that it is the same the entire length of the line.
These two lines are congruent (the same) so we can set them equal to each other and solve.
5x-4=3x+6
The first thing we need to do is subtract 3x from both sides leaving us with 2x-4=6
Now we can add 4 to both sides leaving us with 2x=2
Now we need to divide both sides by 2 to get x alone.
Giving us our final answer of x=1
Answer:
-4
