What is the relation between the variables in the equation x^4/y=7?

So, the relation between variables are

Step-by-step explanation:

We are given

Since, we have to find relation between variables

so, we can solve for y

Firstly, we will multiply both sides by y

we can simplify it

we can isolate y

so, we can divide both sides by 7

so, we get

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
