Answer:
Below.
Step-by-step explanation:
7P4
= 7! / (7-4)!
= 7*6*5*4*3*2*1 / ( 3*2*1)
= 7*6*5*4
= 840.
12C5
= 12! / (12-5)! 5!
= 12*11*10*9*8*7*6*5*4*3*2*1 / ( 7*6*5*4*3*2*1 * 5*4*3*2*1)
= 12*11*10*9*8 / 5*4*3*2*1
= 792.
9. One is 6 over par, the other is three under, so subtract first-second = 6-(-3) = 9
Answer:
-2=x
Step-by-step explanation:
4x+12=-2x
Subtract 4x on both sides
12=-6x
Divided by -6 on both sides
-2=x

Step-by-step explanation:
The volume of the pyramid is 2496 cu.m.
<h3>What is a Pyramid ?</h3>
A pyramid is a three dimensional structure which has a polygon base and in general triangular faces which join at the top .
It is given that
A pyramid
has a 4 m by 4 m square top
Height = 12 m
Base = 20 m
The volume of a square pyramid with a
is given by
V = (1/2) * ( Area of base + Area of
) * height of the
from the base
V = 0.5 * ( 20 *20 + 4*4 ) * 12
V = 2496 cu.m
The volume of the pyramid is 2496 cu.m.
