Question 1013730: Given the number n, write an expression for . (A) twice the sum n and 5 (b) the sum of twice n and 5
(C)give a numical example that shows these are not the Sam expression

You can put this solution on YOUR website!
twice the sum of n and 5 is equal to 2 * (n + 5)

you are resolving the sum of n + 5 first and then multiplying the result of that by 2.

the sum of twice n and 5 is equal to 2*n + 5.

you are resolving twice n first and then adding 5.

twice the sum means you want to take 2 times the sum.

twice n means you want to take 2 times n.

these word problems can sometimes be very ambiguous and difficult to interpret.

here's a reference on key words that might be helpful.
