6 persons * $8= $48
4 popcorns * $6.25= $25
6 persons * $2.75= $16.5 (drinks)
$48+$25+$16.5= $89.50 total
Note: I didn't solve all of them, but hopefully this still helps.
4.
h*b = b*h because of the commutative property. for example if h= 3 and b = 5, 5*3 = 15 = 3*5
2.
a) 2x + 20
b) 5x + 5
c) 10x + 20
d) 72 + 36y
e) 64 + 72
f) 35y + 30
5.
a) 10x + 10y + 10
b) 12x + 20y + 4
c) 56x + 24y + 16
Goodluck with your schoolwork/homework!

Formula
Volume = A_base * height
Solution
Synthetic Division always changes signs of the divisor. Also you add whereas in long division you subtract.
-2 || 2 + 9 - 8 - 36
-4 -10 36
===================
2 5 -18 0
You can eliminate A and B. You are never left with the same power at the beginning when you do a division.
What you are left with is
A_Base = 2x^2 + 5x - 18
Answer: D
