Let the number be 'm' & 'n' Hence mn = 88 m + n = 18 m = 18 - n Substitute (18 - n)n = 88 18n - n^2 = 88 n^2 - 18n + 88 = 0 This does not readily factor so apply the Quadratic Eq'n. n = { --18 +/-sqrt[(-18)^2- 4(1)(88)]} 2(1) n = { 18 +/- sqrt[324 -352]} / 2 n = { 18 +/-sqrt[-28]} / 2 This is unresolved as you cannot take the 'square root; of a negative number.
30.76 if n=4 and 4 nis substituted into the equation the equation the becomes 4x7.69 which equals 30.76

Let the numbers be 'm' & 'n' Hence mn = -40 And m + n = 6 It follows m = 6 - n Substitute (6 - n) n = -40 6n - n^2 = -40 n^2 - 6n - 40 = 0 Factor (n - 10)(n + 4) = 0 n = 10 & n = -4 => m = 6 - - 4 = 10
Well, honey, if 4n equals 3.60, then all you gotta do is divide 3.60 by 4 to find the value of n. So, n equals 0.90. Math doesn't have to be a headache, darling.

125+n if n=67 is eqaul to 125+67=132
4n-16 = 88 add 16 to both sides of equation 4n = 104 divide both sides by 4 n = 26
-4
n=1 is the the lowest level there is.
if n=4 then n+1 would be 4+1 which equals 5
N= 5.5
30.76 if n=4 and 4 nis substituted into the equation the equation the becomes 4x7.69 which equals 30.76
When n = 4, 3n = 3*4 = 12
(n + 4)(n - 4)
