Answer:
(x+3)²-11=0
Step-by-step explanation:
0=9(x2+6x)-18
0= 9x² +54x-18
0= 9( x²+6x-2) taking 9 common
0= x² +6x-2 (breaking the mid term to find the second element of the square
0 = (x)² +2(x)(3) +(3)² -2 -9 adding and subtracting the second element
0= (x+3)² -11 summing up
I guess the mean is always
this question is not clear.
The answer to 9!/3! Is 60480
7 is a prime number, which means it can't be simplified. This fraction is already in simplest form, also because 25 and 7 don't have any common factors.
The pyramid formula:
The volume in this case would be:
1/3×7.9×4
=79/30×4
=10.5333...
≈10.5 m^3
