Answer:
44.0 cm.
Step-by-step explanation:
The formula for the circumference of a circle is

So we can substitute 7 for r and 3.14 for pi:
cm
And since we're rounding to the nearest tenth, the answer is 44.0 cm.
The answer is (A) 15.
(6x -10) makes 80 and (6x+10) makes 100
together that equales 180 degrees. since it is a straight line the sum of the the two would have to equal 180. hope this helped :D
Answer:
a and -b is the answer
Step-by-step explanation:
(x-a)(x+b) = 0
x-a = 0 and x+b = 0
then
x = a and x = -b
Distance Formula: d = √(x₂ - x₁)² + (y₂ - y₁)²
(-6 , 2) and (8 , 10)
x₁ y₁ x₂ y₂
d = √(8 - (-6))² + (10 - 2)²
d = √(8+6)² + (10 - 2)²
d = √(14)² + (8)²
d = √(196) + (64)
d = √ 260
d = 2√65
I think this is right, but I am not sure.
