Start with the standard form of a circle, where 
is the center of the circle and 
is the radius.
Plug in the known values.
This is the circle's equation in standard form.
Store A video price is $20.76
Store B video price is $20.65
So the answer is Store B and it is cheaper by 11 cents
hope this helps and that i get the brainliest answer
Answer:32sq cm
Step-by-step explanation:
area of square 36
sides are then 6 by 6
6+6+6+6=24
24 can be made into 4+4+8+8 8 is twice as much as 4 8x4=32
A. Let x represent the number of miles and y represent the total price.
y=3x+15
B. Using the equation we just wrote, replace the x with 45.
y=3(45)+15
Now multiply 45 by 3.
y=135+15
And finally add together 135 and 15.
y=150
The total cost of a 45 mile taxi ride would be $150.00.
4n-40=7(-2n+2)
4n-40=-14n+14
subtract -4n from both sides
-40 = -18n +14
subtract -14 from both sides
-54=-18n
divide both sides by -18
3 = n
