Benjamin writes an expression for the sum of 1 cubed, 2 cubed and 3 cubed. What is the value of the expression?

1 answer:

8 0

So the "sum" means to add all of the terms: 1³ + 2³ + 3³

1³ is simply 1
2³ is 8
3³ is 27

so, from there, you just add all of those terms: 1 + 8 + 27 = 36

What is 4x-2+x=-2+2x

Vsevolod [243]

Answer:

x= no solution

Step-by-step explanation:

4x-2+x=-2+2x

We first add 4x+x on the left side.

5x-2=2+2x

We then add 2 to both sides.

5x=2x

The answer is no solution because we got no answer out of the equation.
