The average of the given base lengths is the length of the midsegment:
... (72 + 104)/2 = 176/2 = 88
Answer:
240 m³
Step-by-step explanation:
volume = length × width × depth
240 m³ = 20 m × 1 m × 12 m
Answer: The total cost is 
assuming the cost for 1 adult is 
and the cost for 1 child is 
Step-by-step explanation:
Assuming the cost for 1 adult is and the cost for 1 child is :
and 
Then the expression that gives the total cost 
is solved as:
Answer:
16w^2 - 24w + 9
Step-by-step explanation:
To simplify this, you would use the special product (a - b)^2 = a^2 - 2ab + b^2. We can correlate this with the given term so that,
a = 4w
and
b = 3
Now we just substitute into a^2 - 2ab + b^2
(4w)^2 - 2(4w)(3) + (3)^2
16w^2 - 24w + 9
Ex. 9 divided by 3=3 because 3x3=9
