Answer: sorry but i need points
Answer:
onlyA(1,3)
AnB(2,4)
onlyB(6,8,10)
Step-by-step explanation:
(AUB)-(B)=(onlyA)
(1,2,3,4,6,8,10)-(2,4,6,8,10)=(1,3)
(B)-(AnB)=(onlyB)
(2,4,6,8,10)-(2,4)=(6,8,10)
hope this can help you
Use the distance formula to find the diameter:
d = sqrt((x2-x1)^2 + (y2-y1)^2)
Diameter = sqrt((-2 - -2)^2 + (-2 - 3)^2)
Diameter = sqrt((0)^2 + -5^2)
Diameter = sqrt(5^2)
Diameter = 5
The radius is half the diameter: 5/2 = 2.5 units
-k - ( -8k + 7)
negative sign is outside the parenthesis. so it should be multiplied with -8k and 7
-k - (-8k + 7) = -k - 8k * (-1) + 7*(-1)
= -1k + 8k - 7
Now -k and 8k are like terms. So, combine them.
= 7k - 7
