The perimeter is the measure around the shape, so just add all the sides together-
6+5x+x+2
6x+8
Since this is a right triangle, you multiply the legs (6 and x+2) and divide by 2
6(x+2)
6x+12
/2
3x+6
Answer:
A=-2
B=-8
Step-by-step explanation:
In order for the system of linear equations to have infinitely many solution, they must be the same equation.
Ax-y=8
2x+y=B
We need to choose A and B so they are the same equation.
I notice they are both in the same form but in the second column you have opposites;
the -y and y.
So im going to multiply either equation by -1 so that part is exactly the same.
Don't choose both; choose only one.
Let's multiply the first equation by -1.
Doing this gives us the following:
-Ax+y=-8
2x+y=B
So now we can choose A and B so these equations appear exactly the same.
We need -A=2 and B=-8.
-A=2 implies A=(opposite of 2) which is -2.
Conclusion:
A=-2
B=-8
Answer:
Hi,
a=b+3
Step-by-step explanation:
Thus:
c+2b+8-4a=c-a-b-1
3b-3a=-9
<u>a=b+3</u>
You purchase 4 videos
The original price of each video is x dollars
You decide to purchase the limited edition versions of the videos for an additional cost
Your total cost is (4x + 20) dollars
So, total additional cost is $20
since, we are purchasing 4 videos
so, additional cost in each videos is
So, limited edition cost additional $5 per videos.........Answer
Answer:
-2 and 3
Step-by-step explanation:
These two are slopes. All three are technically slopes but a slope of 0 is just a horizontal line.
