The answer to that is (x^4 y^6+1)(x^8 y^12-x^4 y^6+1
Answer:
Step-by-step explanation:

To make this easier, to get ride of the fractions, we can multiply both sides by 4

now use the distributive property

now we want to isolate x to one side and isolate all the constants to the other

now simplify

to test, we can plug in back to the original

it works
That answer will be 7.
Explanation:
=1-3+9
=10-3
=7

Answer:
1 toast costs $0.30 and 1 egg cost $0.60
Step-by-step explanation:
Let price of 1 egg be
and price of 1 toast be 
<u>"$1.50 for 2 eggs and one piece of toast":</u>
We can write 
<u>"$.90 for one egg and one piece of toast":</u>
We can write 
Now, we can solve the first equation for t and substitute that into 2nd equation and solve for e:

Now using the value of e (0.6) and putting it back in the first equation, we will get t:

Hence, 1 toast costs $0.30 and 1 egg cost $0.60
