The equation is 4 meatballs for every adult and 3 for every child. Replace a and c and solve:
M = 4(20) + 2(8)
M = 80 + 16
M = 96
They need 96 meatballs.
I need more information about the triangle before I am able to answer your question.
Part A:5=2x^2-x^2+13
5=x^2+13
0=x^2+13-5
0=x^2+8
Part B:5=2x^3-x^3+13
5=x^3+13
0=x^3+13-5
0=x^3+8

Answer:
B, F
Step-by-step explanation:
The volume is the product of the dimensions:
V = LWH
V = (b^2)(3c^2)(2c^1) = (3·2)(b^2)(c^(2+1))
V = 6b^2·c^3 . . . . . matches B
__
For b=3 and c=2, the volume is ...
V = 6(3^2)(2^3) = 6(9)(8)
V = 432 . . . . cubic inches . . . . matches F
B. Parallel faces
Not all sides need to be parallel and a polygon has only 1 face unless cut
