Use the distance formula 

d  = sqrt ((y2-y1)^2  + (x2-x1)^2))

    =   sqrt ( (5 sqrt2 - sqrt2)^2  +  ( -3sqrt5 - sqrt5)^2)
  
   =     sqrt [( 4sqrt2)^2 + (4sqrt5)^2]

   = sqrt   (32 +  16*5)  =  sqrt 112  = sqrt16 * sqrt7  = 4 sqrt7

The answer is  4 sqrt7

What is the volume of a frustum of a rectangular pyramid if one base has measurements 6 ft. × 8 ft., the other base has measurem
RoseWind [281]
To solve this, we use the formula for the volume of the frustum of a cone which is expressed as:

<span>V= (H/6)[WL + (W+a)(L+b) + ab]
</span>V = 3/6 [(6 ft. × 8 ft.) + (6 + 14)(18 + 8) + (<span>14 ft. × 18 ft.)]
</span>V = 409.98 ft^3 <-----OPTION C
