2(2x + 3) + 2(x=1)
if they give you x just sub in
1/3x>-2=1>3x.-2
=1>-6x
=-1/6>x
In Sunday she babysits 1 hour and 23 minutes,in Saturday she babysit 1 hour and 39 minutes.In total it’s 3 hours and 12 minutes.
Perimeter=4h+4
If the base is 2 more than the height, it gives us the equation:
b=h+2
The equation for the perimeter of a rectangle can be though of as 2b+2h, so substituting in (h+2) for b from the first equation, we get 2(h+2)+2h.
This can be simplified to be 2h+4+2h or 4h+4
I think something is not right here, the answer supposed to be 8
