4n + 5

n = 1 7n + 6n - 5 = 4n + 4 13n - 5 = 4n + 4 13n - 4n - 5 = 4n - 4n + 4 9n - 5 = 4 9n -5 + 5 = 4 + 5 9n = 9 n = 1

yes they are

12 times 5 plus 25 is equal to 85.

The answer depends on the value of x.

If you mean +20 then 5(4n-11)-3n+20 simplifies to 17n-35 and so therefore both expressions are equal

It is 12n2 + 3n - 58

It can be (for x = -2.5) but not for any other value of x.

If you mean: 4n^2-60n+200 = 0 then the solutions are n = 10 or n = 5

Starting from 1, your get: [4n + 5] = 9, 13, 17, 21, 25 Basically you find the first one and add 4 each time.

Using the discriminant of b^2 -4ac = 0 the value of k works out as -2

4 and the two equal roots are 2/5 and 2/5

Points Value = 5 Points Plus Value = 7

for n=4: (4 x 5) + 4 = 24

Use the remainder theorem:- f(x) = x3+nx2+3x-5 f(x) becomes f(2) because the divisor is x-2 and 2-2 = 0 f(2) = 8+4n+6-5 = -3 f(2) = 4n+9 = -3 f(2) = 4n = -12 f(2) = n = -3 So the value of n in the expression is -3 Check: f(2) = 8+(4*-3)+6-5 = -3

7n + 2 = 4n + 17Subtract 2 from each side:7n = 4n + 15Subtract 4n from each side:3n = 15Divide each side by 3:n = 5

It is a linear equation in one unknown variable, n. Its solution is n = 1
