What the answer to this equation X/8+4=5 ?

The answer to this equation is 8

Step-by-step explanation:

First: Subtract

meaning that 5 is greater than 4.

You still need another number to make it equal than or greater than or equal to five.

Since 5 minus 4 does equal 1

You need somewhere to divide it from to get 1 so you can add up the 4 to it and get the answer to the equation.

Lastly: Divide

Now, if you do 8/8 which equals 1, 1+4 = 5; Now everything is, equaled up!

So in conclusion...

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
