Answer:Simplifying

3k + 9 + -1k + -17 = 0

Reorder the terms:

9 + -17 + 3k + -1k = 0

Combine like terms: 9 + -17 = -8

-8 + 3k + -1k = 0

Combine like terms: 3k + -1k = 2k

-8 + 2k = 0

Solving

-8 + 2k = 0

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + 2k = 0 + 8

Combine like terms: -8 + 8 = 0

0 + 2k = 0 + 8

2k = 0 + 8

Combine like terms: 0 + 8 = 8

2k = 8

Divide each side by '2'.

k = 4

Simplifying

k = 4

Find two consecutive odd integers whose product is 99.​
kherson [118]

Given:

Product of two consecutive odd integers is 99.

To find:

The two consecutive odd integers.

Solution:

Let the two consecutive odd integers are x and (x+2).

Product of two consecutive odd integers is 99.

x(x+2)=99

x^2+2x-99=0

Splitting the middle term, we get

x^2+11x-9x-99=0

x(x+11)-9(x+11)=0

(x+11)(x-9)=0

x=-11,9

If x=-11, then second odd integer is

-11+2=-9

If x=9, then second odd integer is

9+2=11

Therefore, the two consecutive odd integers are either -11, -9 or 9, 11.
