5m3 + 4n is an algebraic expression.
It is an expression that can be simplified to -4n-1
1
2(15-2n) Look for the greatest common factor of 30 and -4n. Put it out front, then divide each term by this number to get the expression in the parentheses. 30/2 = 15, -4n/2 = -2n.
It is: 4n-13
24n
5m3 + 4n is an algebraic expression.
The nth term is: 4n
4n x 2 = 8n
Let the required answer be represented by 'y' and the variable number by 'n'. Then y = 4n + 3
It is an expression that can be simplified to -4n-1

11m + 4n - 3m +11n = 8m + 15n
Yes
2(15-2n) Look for the greatest common factor of 30 and -4n. Put it out front, then divide each term by this number to get the expression in the parentheses. 30/2 = 15, -4n/2 = -2n.
4n+3 For n = 1, the expression evaluates to 4+3 = 7 For n = 2, the expression evaluates to 8+3 = 11 For n = 3, the expression evaluates to 12+3 = 15
