3 < x < 13
This is because the sum of two sides must be greater than the length of the third side.
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
To solve this problem you must apply the proccedure shown below:
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
The answer is:
- Gold ring=</span>7053.75 euros
- Silver ring=2351.23 euros<span>

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.
