How do you solve this
IgorLugansk [536]
First lets write out the equation:
-8x + 2x - 16 < -5x + 7x
Lets collect the x values

-6x - 16 < 2x
-8x - 16 < 0    (subtract both sides by 2x to get all the x's on one side)
-8x < 16         ( add both sides by 16 to get all the x's alone)
x < -2             ( divide both sides by -8 to get what just x is) 

So x < -2

<h3>What is a Pyramid ?</h3>

A pyramid is a three dimensional structure which has a polygon base and  in general triangular faces which join at the top .

It is given that

A pyramid \rm frustum has a 4 m by 4 m square top

Height = 12 m

Base = 20 m

The volume of a square pyramid with a  \rm frustum is given by

V = (1/2) * ( Area of base + Area of  \rm frustum ) * height of the  \rm frustum from the base

V = 0.5 * ( 20 *20 + 4*4 ) * 12

V = 2496 cu.m

The volume of the pyramid is 2496 cu.m.
