Answer:
The volume of the given pyramid is 300 cm³
Step-by-step explanation:
The volume of a pyramid,
, is given as follows;

The height of the pyramid = 12 cm
The side length of the square base of the pyramid = 5 cm
The base area of the pyramid polyhedron with square base = 5 cm × 5 cm = 25 cm²
Therefore, by substitution, we have;

The volume of the given pyramid, V = 300 cm³.

change

given you

making x the subject by transferring the -19 to the right hand side of the equation


dividing through by 5


{
}
also given

change the operation sign to =



dividing through by -4


so the truth set is
{x:x>9/4}.
The < sign changes to > because we divided by a negative number when solving for x
B) a=-1, b=5, c=0 would be the correct answer
Answer:
But this condition is not feasible so, from given equation the value of D is not determine
Step-by-step explanation:
Given equation is :

= 22 - 3
Or,
= 18
Or 0 = 18
But 0 ≠ 18
but this condition is not feasible so, from given equation the value of D is not determine .. Answer
