(A) 12n + 14m + 4 B) 2 (7n +3m + 7) c 3 (m + 4n+20) D) 14m + 12m + 4 CHECK ANSWER X 101 Use the expression 10m + 3 (n + 8) + 4 (m - 5) + 9n to find its simplified form Which expression is written correctly in standard form? Be sure to clear the parenthesis first and then combine like terms.​

Answer 1

"A) 12n + 14m + 4" would be the standard form.

Explanation:

the expression written correctly in standard form would be "A) 12n + 14m + 4"

10m + 3(n + 8) + 4(m - 5) + 9n you need to first clear the parenthesis by applying distributive property:

10m + 3(n + 8) + 4(m - 5) + 9n = 10m + 3n + 24 + 4m - 20 + 9n

After that you combine like terms

= 10m + 4m + 3n + 9n + 24 - 20 = 14m + 12n + 4

"A) 12n + 14m + 4" would be the standard form.
