Arectangular box is x feet long and x feet wide. the volume of the box is (4x^8 + 3x^6) cubic ft. what polynomial represents the height of the box in feet?

Hence, the height, in feet, of the rectangular box is given by the polynomial  

Step-by-step explanation:

The volume of a rectangular box is given by the formula:

We are given , length = x, and width = x , plugging these into the formula and figuring out height:

Hence, the height, in feet, of the rectangular box is given by the polynomial  

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
