Answer:
x^2 -14x +49
( x-7)^2
Step-by-step explanation:
x^2 -14x
We are completing the square
Take the coefficient of x
-14
Divide by 2
-14/2 = -7
Square it
(-7)^2 = 49
Add it
x^2 -14x +49
Take the -7
( x-7)^2
Answer:
44.5 yards
Step-by-step explanation:
Start with the formula of the circumference of a circle.
C = πd
Now all you have to do is plug in the numbers.
279.46 = (3.14)d
Divide both sides by 3.14
d = 89
But since you're finding the radius, you have to divide the diameter by 2.
89/2 = 44.5
