So represent missing number with x
x means unknown so
x+-1=+1
adding a negative means subtraction
x-1=1
you can do anything to an equation as long as you do it to both sides
add 1 to both sides
x+1-1=1+1
x+0=2
x=2
the number is 2
(n-4)(n+11) so pretty much B
Answer:
because of 180
Step-by-step explanation:
Answer:
AB=8.94427191 (leave a comment if you need it rounded)
Step-by-step explanation:
First, plug these into the distance formula. (d= √(x2-x1)^2+(y2-y1)^2)
d=√(-3-5)^2+(4-8)^2
Now, solve the problem.
d=√(8)^2+(-4)^2
d=√64+16
d=√80
d=8.94427191

Answer:
surface area = 8704.08 cm²
Step-by-step explanation:
The surface area of a cone is given by the formula;
SA = πr² + πrL
Where r is radius and L is slant height
We are given;
Diameter = 24cm
Slant height; L = 41 cm
We are told that this new cone has a diameter that is triple of the one given.
Thus, new diameter = 24 x 3 = 72 cm
Thus, Radius; r = 72/2 = 36 cm
SA = π(36)² + π(36)(41)
SA = (3.14 * 1296) + (3.14 * 1476)
SA = 8704.08 cm²
