What is 4 equals 5n plus 6n2?
4 = -5n + 6n2 if you want to solve for n: 6n2 - 5n - 4 = 0 (3n - 4)(2n + 1) = 0 3n - 4 = 0, n = 4/3 2n + 1 = 0, n = -1/2 n = {-1/2, 4/3}
How do you solve 1 minus 7n equals 15 minus 5n?
1 - 7n = 15 - 5n Add 5n to each side: 1 - 7n + 5n = 15 -5n + 5n ie 1 - 2n = 15; subtract 1 from each side: -2n = 14 divide both sides by -2: n = -7
If 5n plus 7 equals -41 what is n?
5n + 7 = -41 5n = -48 n = -48/5 n = -9.6
How do you find the sequence of 35 - 5n?
Substitute the values 1, 2, 3, etc for n in 35 - 5n
5n plus 15 equals 25 solve for n?
5n+15 = 25 5n = 25-15 5n = 10 n = 2
9 - 5n plus 1 equals 15?
9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
Solve this problem 9 minus 5n plus 1 equals 15?
9-5n+1 = 15 -5n = 15-9-1 -5n = 5 Divide both sides of the equation by -5 to find the value of n: n = -5
What is 4 equals 5n plus 6n2?
4 = -5n + 6n2 if you want to solve for n: 6n2 - 5n - 4 = 0 (3n - 4)(2n + 1) = 0 3n - 4 = 0, n = 4/3 2n + 1 = 0, n = -1/2 n = {-1/2, 4/3}
5n plus 3 equals 14-6n what is n?
5n + 3 = 14 - 6n <=> 5n +6n = 14 - 3 <=> 11n = 11 => n = 11/11 = 1
What is 25n2-1?
It's the product of (5n+1) and (5n-1). It represents a number which you can't identify unless you know what number 'n' is.
How do you solve 1 minus 7n equals 15 minus 5n?
1 - 7n = 15 - 5n Add 5n to each side: 1 - 7n + 5n = 15 -5n + 5n ie 1 - 2n = 15; subtract 1 from each side: -2n = 14 divide both sides by -2: n = -7
Solve for n in 5n - 25 equals 10?
5n-25 = 10 5n = 10+25 5n = 35 n = 7
How do you factor 4 - 20 n?
-16
What is the nth term for 2 7 12 17?
t(n) = 5n - 3
If 5n plus 7 equals -41 what is n?
5n + 7 = -41 5n = -48 n = -48/5 n = -9.6
5n plus 8 43?
If 5n + 8 = 43, then n = 7
How do you factorise 2nxn plus 5n plus 3?
(2n+3)(n+1)=2n2+5n+3.
