4 right triangular pyramids make a cube now instead of a cube suppose there's a square prism
4 times volume of triangular pyramids should be equal to the volume of square prism
(4bh)/3 = a^2 * h
but since its a square at the base, let us suppose that 2ar(triangle at base) = area of square
(2*a^2h)/3=a^2 * h
which gives 2/3=1
which should mean that a cube is not made of 4 pyramids
but we know that is not true
how?

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
