If R = 1/2 D, then D = 2R. if the radius is 5.5, then plug it in and you get 5.5 times 2. Or 11.
Answer:
1
Step-by-step explanation:
f(x)=x^3+2x^2-x-1
f(1)=1^3+2(1)^2-1-1
f(1)=1+2*1-1-1
f(1)=1+2-1-1=3-1-1=2-1=1
Answer: the factor that we can multiply by itself to get that number
Step-by-step explanation:
For example, the square root of 4, is 2 because 2*2 is 4.
