Answer:
55.4 in³
Step-by-step explanation:
The formula for the volume of a pyramid can be found:
V = 
, where B = area of the base and h = height of the pyramid
Since the base is a triangle, we need to use the formula for the area of a triangle:
A = 
= 
Next, multiply the area of the base by the height of the pyramid:
17.67 x 9.4 = 166.098 ÷ 3 ≈ 55.4 in³
With process of elmination the answer is C because all the rest are the same number but placed it is different order.

Pascal's triangle up to the 5th iteration is
This tells us
so the second term in the expansion is
Factor the numerator to get:
(-3z(z+5))/(z+5) now you notice that (x+5) cancel out leaving:
-3z
The distributive property is a(b+c) = ab + ac or a(b-c) = ab - ac
So here are some potential answers:
8(50 + 4) = 8·50 + 8·4
8(60 - 6) = 8·60 - 8·6
I prefer the first answer
