1/2(x + 4) = -12
1/2x + 2 = -12
1/2x = -10
x = -20
Answer:
Step-by-step explanation:
2a.x=10+5
b. x=11-7
C. x=5*2
Nice
area=pir^2
the areas are
pir^2+pi(2r)^2
they add to 8pi
8pi=pir^2+pi(2r)^2
undistribute pi
8pi=pi(r^2+(2r)^2)
divide both sides by pi
8=r^2+(2r)^2
expand
8=r^2+4r^2
add
8=5r^2
divide by 5
8/5=r^2
sqrt both sides
√(8/5)=r
double since it is double
2√(8/5) is radius of bigger aka (4√10)/5
radius=(4√10)/5
Answer:
Step-by-step explanation: you have to divide 112 by 14
