It is the exact middle of a coordinate plane, the only point where the x axis and y axis meet together, and it is not in a specific quadrant
Answer:
A=2, B=3, C=5
Step-by-step explanation:
Two polynomials are equal for all values of the variable if the corresponding coefficients are the same. The way to solve the problem is to multiply the RHS, rewrite it in a more orderly way

Now, for the two polynomials to be the same we need to have, at the same time

You might notice that we have more conditions than variables, but you can consider one of the two in the middle as a "check" option.
Now, grabbing the value from the first condition into the second we get B=3. Replacing both value in the third we see that the equality still holds, and replacing into the fourth we get C =5.
78, because you have to do the inverse operation so 80/2= 40 then 40-1= 39 and 39*3 = 78
Answer:
C
Step-by-step explanation:
To convert kilograms into grams, you need to multiply the number you are converting by 1000.
I hope my answer helpe! :)
The values are
and 
Explanation:
The expression is 
Simplifying, we get,

Since, both sides of the expression are equal, we can equate the corresponding values of A, B, C and D.
Thus, we get,
⇒
and 
Also, equating,
, we get,
and 
Thus, the values are
and
