The third one is r=-10 (don't forget the negative!)
The fourth one is p=-3 (again, watch for the negative)
((I can't get the fifth one, sorry. You might want to repost another question with just that one))
The sixth one is w=35.
Hope this helped a little bit! Sorry I couldn't help with all of them .-. Good luck though!
Answer:
576
Step-by-step explanation:
3*2 = 9
4*3 = 64
9 x 64 = 576
if x^2=40 you would need to square root both sides to get x alone therefore x=6.3
D = 11
