Answer:
16
Step-by-step explanation:
-12
if a=-2 and b=-5
(18-(-2×-5))+4(-5)
(18-(10))-20
8-20
just gotta plug in the given into the equation
because r=d/2 it will be
22.5/2=r
r=11.25m
c=2×3.14×11.25
c=70.65msquare
c=7065/1oo
Answer: x=-3
First you add 3x+5x cause they are both variables.They equal 8x.
Then you subtract 7x from both sides to get x+17=10
then you subtract 17 from both sides.
you will get x= -3
Hope that helps!
