Volume of pyramid = 1/3 (B) (h)
B is the area of base length.
V=1/3(121)(12)
V=484 cm^2
Answer:3x-7=3(x-3)+2
3x-7=3x-9+2
3x-7=3x-7
Group like terms
3x-3x=-7+7
0=0
Step-by-step explanation: the above calculations implies that, the equation has no solution, since all the unknown variables also vanish to zero.

Step-by-step explanation:
SOLVING THE INEQUALITY
TO MATCH OPTION A
Considering the inequality





Thus,

Therefore, the inequality
has the solution
which matches the option A.
SOLVING THE INEQUALITY
TO MATCH OPTION B
Considering the inequality








Thus,
![-4x+7\ge \:27\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-5\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-5]\end{bmatrix}](https://tex.z-dn.net/?f=-4x%2B7%5Cge%20%5C%3A27%5Cquad%20%3A%5Cquad%20%5Cbegin%7Bbmatrix%7D%5Cmathrm%7BSolution%3A%7D%5C%3A%26%5C%3Ax%5Cle%20%5C%3A-5%5C%3A%5C%5C%20%5C%3A%5Cmathrm%7BInterval%5C%3ANotation%3A%7D%26%5C%3A%28-%5Cinfty%20%5C%3A%2C%5C%3A-5%5D%5Cend%7Bbmatrix%7D)
Therefore, the inequality
has the solution
which matches the option B.
SOLVING THE INEQUALITY
TO MATCH OPTION C
Considering the inequality


∵ 




Therefore, the inequality
has the solution
which matches the option C.
SOLVING THE INEQUALITY
TO MATCH OPTION D
Considering the inequality






Thus,

Therefore, the inequality
has the solution
which matches the option D.
