#1 w=9 because:
2w+2(2w+3)=60
2*2w=4w and 2*3=6
2w+4w+6=60
Then: 2w+4w= 6w
6w+6=60
I just tried each answer I knew it had to be 8 or 9
So I tried 8 and it didnt work then I tried 9 and it did
6*9= 54+6=60
w=9
#2 I have a picture for this one I worked it out on paper. Check out the photo for the answer :)
Hope this helps!
