3n + 2n = 25 5n = 25 n = 5
It is an expression that can be simplified to: 3n-10
It is: 4n-13
-n + 4(n + 1) = 3n+4
3n + 7 = 163n + 7 - 7 = 16 - 73n + 7 - 7 = 16 - 73n = 16 - 73n = 93n/3 = 9/33n/3 = 9/3n = 9/3n = 3Check:3 x 3 + 7 =? 169 + 7 =? 1616 =? 16n=3 is the correct answer.
2n(3n + 8)
6n2 + 16n can be factorised to give 2n(3n + 8) so the highest factor is 2n.
8m + 3n - 5m + 10n = 3m +13n
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
3n + 2n = 25 5n = 25 n = 5
It is an expression that can be simplified to: 3n-10
It is a algebraic expression which can be simplified depending on the plus or minus values of 3n and 10n which have not been given.
It is: 4n-13
-n + 4(n + 1) = 3n+4
3n + 3(6 + 7n) = 3n + 18 + 21n = 24n + 18
3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6
3n + 7 = 163n + 7 - 7 = 16 - 73n + 7 - 7 = 16 - 73n = 16 - 73n = 93n/3 = 9/33n/3 = 9/3n = 9/3n = 3Check:3 x 3 + 7 =? 169 + 7 =? 1616 =? 16n=3 is the correct answer.
