Answer:
4000 
Step-by-step explanation:
V = 1/3(Bh) where B is the area of the base and h is the height of the pyramid
B = 20(20) = 400 h = 30
V = 1/3(400)(30) = 4000 
Given f(x)=2x, if (x)=14, find x
x=3

Answer:</h2>
The first consecutive odd number is: 9
and the second consecutive odd number is: 11
<h2>
Step-by-step explanation:</h2>
Let the two consecutive odd numbers be: a and a+2
( Since, we know that the difference between two consecutive odd or two consecutive even numbers is always 2 )
Now, it is given that:
Three times the first is 5 more than twice the second.
i.e.

Hence, we get:
The first consecutive odd number is: 9
and the second consecutive odd number is: 9+2=11
Answer:
x = 58
Step-by-step explanation:
The angle formed by two secants
= 1/2(difference of intercepted arcs)
51 = 1/2 (160 - x)
Multiply each side by 2
51*2 = 2*1/2 (160-x)
102 = 160-x
Subtract 160 from each side
102-160 = 160-160-x
-58 = -x
Multiply each side by -1
58 =x
