This is how you do it
4x-6+3x+6
4x+3x
7x
Answer:
7
Step-by-step explanation:
Thing about centroids is they create segments that are spilt with one piece
and the larger piece
.
So, if the whole segment is 21, then the large piece is
of 21. The small piece is
of 21.
TE = 21 ·
=
= 7
1.325 because 1000 is 1 and then all is left is .325
Coordinates of the center you can find from
x-3=0 and y+5=0
x=3 and y=-5
(3,-5) is the center of the circle.
25 is a square of the radius.
r²=25, so
r=5
Center (3,-5), r=5
So, the answer is D.
