PLEASE HELP
Aliun [14]

Hello from MrBillDoesMath!

Answer:

(x^4-2) (x^4 -1)


Discussion:


Let u = x^4, then

x^8 - 3x^4 + 2

= u^2 - 3u + 2

= (u -2) ( u -1)

= (x^4-2) (x^4 -1)



Thank you,

MrB

 1. You have that:

 - He sales 13 gold rings and 18 silver rings in 9405 euros.
<span> - The cost of the silver ring is three times the cost of the gold ring.

 2. Keeping the information above on mind, you have the following system of equations:

 x: the gold ring.
 y: the silver ring.

 x+y=</span>9405
<span> x=3y

 3. Then, you have:

 (3y)+y=9405
 y=9405/4
 y=2351.23 euros

 x=3y
 x=3(</span>2351.23)
<span> x=7053.75 euros

Write an equation that models this situation.
Nimfa-mama [501]

Answer:

B

Step-by-step explanation:

the ideal way to put the equation would be x= 6 x 8 but since that is not an option B is the answer. the keyword is "each" that allows you to know that you will be multiplying those to numbers.

so the only one that allows you to multiply 6 and 8 is B when you multiply 6 to the other side.
