Answer:
0
Step-by-step explanation
well at least thats my guess!
we have to go by bidmas. so you substitute first!
so its going to be: 3(-1)(4(-1)+5)+3
all I did is that I replaced all p's by -1 and then you multiply it!
so its gonna be: -3(-4+5)+3
you first solve what's in the brackets which is -4+5 so the answer is 1 like this: -3(1)+3 now its much simpler. all we have to do is to expand the bracket so its going to be -3+3 so the answer is 0!

Answer:
8 in
Step-by-step explanation:
RA = 4 in, RB = 2 in
oil height in A = hA = 2 in
Find oil height in B = hB
volume of oil in A = VA = π*RA² * hA
equal amount means volume of oil in B VB = VA
But VB = π*RB² * hB
so π*RA² * hA = π*RB² * hB
then
hB = hA *(RA/RB)² = 2 * (4/2)² = 8 in
