If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.
n ___ = 3 2+5 n = 3(2+5) n = 3(7) n = 21
no
1: (n-2)2 2: n-22 3: n+2n-2 4: n-2n+2 If I understand your question correctly (it is really confusing) then none of the expressions 2 3 or 4 equal the first expression.
That question has no answer since n must equal 3 and if you substitute n in 3n-2, you will see that it does not equal 3, it equals 7.
The question is ambiguous. Does "2 over 3 times n" mean 2/(3*n) or (2/3)*n

this is called an algebraic expression. the letter "m" and "n" are called variables. you need to find out what number you can replace the "m" and "n" buy so the equation on the left side equal 8 lets try m=3 and n=2 If we do this then... (3 x 3 ) + (2 x 2) = 8 Is this correct.. well lets see... 3 times 3 is 9 and 2 times two is 4. if you add 9 and 4 that equals 13. so these numbers are not correct. try m=2 and n=1 If we do this then... (3 x 2) + (2 x 1) = 8 Is this correct... well lets see... 3 times 2 is 6 and 2 times 1 is 2. if you add 6 and 2 that equals 8. these are the correct numbers that "m" and "n" should equal!
4*(n + 1) = 6*n*3
(2 / 3) times 3 = 2
n + (2 x 3) = 21 Therefore, n = 21 - (2 x 3) n = 15
In the literal numeric sense, "2 6" is not equal to "3 9", however if you expressed it as a function, seeking the multiplier-relationship between each pair of numbers then this would be true: 6/n = 2 would equal 9/n = 3, because in both cases n = 3.
