Answer:
b. 75.40
Step-by-step explanation:
The circumference of a circle is the perimeter of the circle. To find the perimeter we would use the formula ⇒ 2 × π × r ⇔ or π × d ← where r is the radius and d is the diameter .
So lets substitute in the values
2 × π × r
Radius = 12
2 × π × 12 = 24 π = 75.3982236862
So the answer is b. 75.40
Answer: The answer is A
Step-by-step explanation: Add the coefficient of x to the both sides.
X²+4x=12
X²+4x+4=12+4
X²+4x+4=16
X²+2x+2x+4=16
X(x+2)+2(x+2)=16
(X+2)(x+2)=16
(X+2)²=16
6,8
9,7
13,1
im srry thats all i know :(
No, 1/8 is smaller because 2/10 is equivalent to 1/5 and 1/5 is larger than 1/8.
Combine like terms.
2x + 6 + 6x - 1
8x + 5
