80 inches or feet.. I think you are suppose to multiply 40x2 sorry if im wrong
Hello! your answer would be infinite solutions, or b! hope this helped! ;)
Answer:
B
Step-by-step explanation:
Start by using the distance formula to find the raidus
The two points are (-2,1) and (-4,1)
√((-4+2)²+(1-1)²)= 2
The radius is two and we have our center which means we can write
(x+2)²+(y-1)²=4
now it's just a matter of expanding everyhting
x²+4x+4+y²-2y-3=0
x²+y²+4x-2y+1=0
This is equal to B
Answer:
Yes it is simplified
Step-by-step explanation:
2x^2 is not a like term to 2x because 2x does not have an exponent. Therefore, you cannot add 2x to 2x^2. So it is as simplified as it can be at this point
If you have a calculator I would suggest using that, but otherwise here's the process:
170
+130
--------
Add the zeros.
0
+0
-----
Add 70 and 30.
70
+30
------
Carry the 1 on the 10
Add 100, 100, and 100 (From the 10)
100
100
+100
--------
Add 300, 0, and 0.
300
0
+ 0
---------
The answer is 300.
