Three students were asked to evaluate two cubed. The beginning part of their work is shown.

faltersainse [42]

Answer:

Kristen is correct because two cubed is the same as 2x2x2 . The value of two cubed is 8

===================================================

Explanation:

Cubing something means we multiply it by itself 3 times.

A few other examples are shown below

$\text{five cubed} = 5^3 = 5*5*5 = 125\\\\\text{eight cubed} = 8^3 = 8*8*8 = 512$

As the name "cubed" implies, this concept is useful to find the volume of a 3D cube where all the side lengths are the same.

The quotient of 25 and t plus 6 is the same as twice t plus 1. Turn into equation!

KiRa [710]

25/t + 6 = 2t + 1
solve the equation from there
(1- 6)
25/t = 2t + -5
25/t x 2t = -5
50t = -5
t = -1/10
