Determine if the equation is true or false for x = 6 show your work

False

Step-by-step explanation:

Hi there,

In order to solve this, you have to fill in 6 for x.

1. 4 (6) - 28 = ?

2. 24 - 28 = -4

Since 24 - 28 is equal to -4, the first equation is true. For the second equation, we do the same thing:

1. 6 + 3(6) = ?

6 + 18 = 24

Since 24 is not equal to 32, the second equation is false.

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

step-by-step explanation:

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
