<h3>True statement about dollhouse</h3>
The space inside dollhouse 1 can be found using the equation V = 6 (6) (5) + one-half (6) (6) (4).
Space inside dollhouse 1:
V = 6 (6) (5) + 1/2 (6) (6) (4)
V=180+72
V=252 inches
The space inside dollhouse 2 can be found using the equation
V = 6 (6) (5) + 1/3 (6) (6) (4)
V=180+48
V=228
The space inside dollhouse 1 is 24 inches cubed greater than the space inside dollhouse 2.
V1=252
V2=228
Hence:
252-228=24 inches cubed
V1 ≥V2
Therefore the statements that are true about the dollhouses is: 1,4,5.

Answer:
(f∘f)(x) = x⁴ -12x² +30
(g∘g)(x) = x/9
Step-by-step explanation:
a) (f∘f)(x) = f(f(x)) = f(x² -6)
... = (x² -6)² -6
... = x⁴ -12x² +36 -6
... (f∘f)(x) = x⁴ -12x² +30
b) (g∘g)(x) = g(g(x)) = g(x/3)
... = (x/3)/3
... (g∘g)(x) = x/9
The coordinates of the mid-point between points B and C is given by:
(-5, -10).
<h3>What is the mid-point concept?</h3>
The mid-point between two points is the halfway point between them, and is found using the mean of the coordinates.
The points in this problem are given as follows:
B(-40, -30), C(30, 10)
Hence the coordinates of the mid-point are:
