5−(2w−8)=6w−9
Show Steps
Expand 5−(2w−8): −2w+13
−2w+13=6w−9
Subtract 13 from both sides
−2w+13−13=6w−9−13
Simplify
−2w=6w−22
Subtract 6w from both sides
−2w−6w=6w−22−6w
Simplify
−8w=−22
Divide both sides by −8
−8w
−8 =

Hello,
x=r cos t
y=r sin t
x²+y²=r²
r=4 cos t
r=4x/r==>x²+y²=4x
==>(x-2)²+y²=4 (a circle center (2,0),radius 2)
