Answer:
k=9
Step-by-step explanation:
8k-6=(k+3)+6k first remove the unnecsarry parentheses which would make it 8k-6=k+3+6k
then collect the like terms and get 8k-6=7k+3 then move the variable to the left and change its sign to get 8k-7k-6=3.
then collect the like terms a final time which would get you k=3+6 to then get k=9

Answer:
7x^2y^3z^5(x^2y^5 + 2z^6)
Step-by-step explanation:
7x^4 y^8 z^5 + 14x^2 y^3 z^11
try to get the smallest of each number and variable outside if that makes any sense
14 can go into 7 two times so take out 7 and multiply it by the whole thing
7(x^4 y^8 z^5 + 2x^2 y^3 z^11)
then x y and z
7x^2y^3z^5(x^2y^5 + 2z^6)
sorry its kinda hard to see exponents in this form hopefully this helps

The first cell phone bill of Ms. Trowbridge after 40% discount is $51.
What will be the amount of her first cell phone bill?Given information:
The discount on first cell phone bill = 40%
The flat charges on bill = $25
The charge per minute = $0.20
Since $0.20 is charged per minutes, the amount charged for 300 minutes will be :
300 x 0.20 = $60
Her monthly cell phone plan charges a flat monthly fee of $25.00.
the total amount charged will be;
$60 + $25 = $85
There is a 40% discount , then we have 40% of $85
= $34
So, the amount of her first cell phone bill ,
= $85 - $34
= $51.00
Hence, the first cell phone bill of Ms. Trowbridge after 40% discount is $51.

find the distance between the pionts(-5,1) and (4,1)
Explanation:
The formula for calculating the distance between two points is: d = √ ( x 2 − x 1 ) 2 + ( y 2 -y 1 ) 2 Substituting the points from the problem gives: d = √ ( 0 − 5 ) 2 + ( 4 − 1 ) 2 d = √ ( − 5 ) 2 + ( 3 ) 2 d = √ 25 9 d = √ 34 Or d =3 5.8 rounded to the nearest hundredth.

(z^2 + 11z + 18 / z^2 + 14 z + 45) multiplied by (z^2 + 8z + 15 / z^2 + 2z)
Show steps too if you can!
Answer:
[tex] \dfrac{z + 3}{z} [/tex]
Step-by-step explanation:
[tex] \dfrac{z^2 + 11z + 18}{z^2 + 14 z + 45} \times \dfrac{z^2 + 8z + 15}{z^2 + 2z} = [/tex]
Multiply the numerators. Multiply the denominators.
[tex] = \dfrac{(z^2 + 11z + 18)(z^2 + 8z + 15)}{(z^2 + 14 z + 45)(z^2 + 2z)} [/tex]
Factor every polynomial.
[tex] = \dfrac{(z + 2)(z + 9)(z + 5)(z + 3)}{(z + 5)(z + 9)z(z + 2)} [/tex]
Divide the numerator and denominator by equal factors.
[tex] = \dfrac{z + 3}{z} [/tex]
