(I don't have a lot of points left sorry) Steven is 5.6 ft tall and casts a shadow that is 12.4 ft long. A nearby tree casts a shadow that is 31 ft long. How tall is the tree?

I think the answer is 17.4 i don't know if its right

Step-by-step explanation:

5.6+6.8=12.4

so what you have to do is find what number the tree has to add by to get to 31

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

2x^2+5x+17

your welcome. : )
