Answer:

Step-by-step explanation:
To find the circumference of a circle, you can multiply the value of the diameter of the circle with the value of pi.



Here we can simplify the product by multiply the square root 2 with square root 2 first.

=3*2
=6
So answer is 6
Step-by-step explanation:
Given points are (-2,5) and (3,-17)
to find midpoint, use this formula
( x1+x2/2 , y1+y2/2)
where points are a(x1,y1) and b(x2,y2)
coming to the question,
midpoint is :
[ (-2-3)/2 , (5-17)/2 ]
[ -5/2 , -12/2 ]
[ -2.5 , -6 ]
OPTION
IS CORRECT
It has three lines of symmetry.
8/1 + (x-1)/(x+4)
You need the same common denominator (bottom number) to be able to add together so multiply 8 by (x+4) to both bottom and top
8 (x+4)/(x+4) + (x-1)/(x+4)
Add
8 (x+4)+(x-1)/ (x+4)
Distribute the 8 to (x+4)
8x+32+x-1 / x+4
Simplify
9x+31/x+4
