The volume of a pyramid is 50 3 . What is the volume of a prism that has a congruent base and is the same height as the pyramid?
Darya [45]

Answer:

150 mm^3

Step-by-step explanation:

The formula of a pyramid is

V=1/3(Bh)

The formula for a rectangle is

V=(Bh)

They both have the same Bh, so because the formula of a pyramid states that it's 1/3 of Bh, and 1/3 of Bh = 50, the volume of a whole Bh is 150mm^3.

Hope this makes sense

Simplify the expression x^2+x-2/8x^2+4x/3x^2+10x+8
irina [24]

Answer:

Step-by-step explanation:

x² + x  - 2 = x² - x +2x -2 = x(x - 1) + 2*(x-1)  = (x-1)(x+2)

8x² + 4x = 4x ( 2x + 1)

3x² + 10x + 8 = 3x² + 6x + 4x + 4*2  =3x  * (x + 2) + 4 * ( x + 2) = (x + 2)(3x + 4)
