Answer:
-30.6
Step-by-step explanation:
You can use a calculator or you can think and be well if theres a number line theres a right part so -100.55 so then yo move 69.95 spaces
24.5=-2.5c-4c
24.5=-6.5c
49=-13c
3.77=-c
c=-3.77
Instead of trying to find the exact answer on the internet, I would suggest looking up how to turn decimals into fractions. But I will give you a hint, it would be a mixed number
Factor the equation:
(x-6)(x+1)
Check:
-6+1=-5
-6*1=-6
Use the zero product property
x-6=0
x=6
x+1=0
x=-1
Final answer: x=-1, x=6
Answer: 8 centimeters
Step-by-step explanation: To find the radius of the circle, remember that the formula for the area of a circle is πr² and since we're given that the area of our circle is 64π, we can set up the equation 64π = πr².
To solve for <em>r</em>, we first divide both sides of the equation by π.
On the left side, the π's cancel and we're left with 64 and on the right side, the π's cancel and we're left with r².
So we have 64 = r².
Next, we take the square root of both sides to get 8 = r.
So the radius of our circle is 8 centimeters.
