If x^2 + kx + 6 = (x+n)(x + 3) for all values of x, where k and n are constants, what is the value of k?
A) 5
B) 3
C) 2
D) 1

A) 5

Step-by-step explanation:

We are given that:

Where k and n are constants.

And we want to find the value of k.

We can expand the right-hand side:

Hence:

The coefficients of each term must be equivalent. In other words:

Solve for n:

Now, we can solve for k:

Our answer is A.

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
