A. 0.8 that’s the answer because if you divide 32 by 40 you get 0.8
Just look at coefficient of highest power of x (leading coefficient): 6. It is x^2, so limf(x) x—>infinity and limf(x) x—>-infinity are both infinity
#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!
