2 cubed = 2*2*2 =8. 8+8+8= 24
The expression 48x + 8 can be factored by finding the greatest common factor of the two terms, which in this case is 8. Therefore, we can rewrite the expression as 8(6x + 1). This is the factored form of 48x + 8.

Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.
The expression 9+5 is equivalent.
