Subtract 8 from each side:
-4x = 40
Divide each side by -4 :
x = -10
Answer:
Step-by-step explanation:
The volume of a sphere is given as
and we will use 3.1415 as π:
to get that
V = 268.07 cm³
#1 center (9,6) radius = 10
#2 center (4,-2) radius = 4 square root 2
#3 center (-3,-8) radius = 9
#4 center (-6,5) radius = 2 square root 2
