Which equation shows an example of the associative property of addition? (–4 i) 4i = –4 (i 4i) (–4 i) 4i = 4i (–4i i) 4i × (–4i

i) = (4i – 4i) (4i × i) (–4i i) 0 = (–4i i)

The associative property is:

A + B + C = A + (B + C) = (A + B) + C

And a option that uses this is:

-4i + i + 4i- i = (-4i + 4i) + (i - i)

<h3>Which equation shows an example of the associative property of addition?</h3>

The associative property says that we can write:

A + B + C = A + (B + C) = (A + B) + C

So, we can perform the sum in any order we want to.

Then for the given case we would have:

-4i + i + 4i- i = (-4i + 4i) + (i - i)

Where we sum in the order we want to get it equal to zero.

F(x) = ax2 - 12, g(x) = 2x +3, and f(3) = 24. What<br> is the value of g(f(2)) ?
elixir [45]
<h2>Answer:    g(f(2))  = 11</h2>

Step-by-step explanation:

g(f(2)) is substituting the value of f(2) for x in g(x). But we must first find f(2).

We know that f (x) = ax² - 12

Since f(3) = 24

  ⇒ a(3²) - 12 = 24

       9 a  = 36

          a  = 4

∴ f(2) = (4)(2²) - 12

         =  4

 

⇒ g(f(2)) = 2(4) + 3

             = 11

antoniya [11.8K]
3M^2 + 11MN + 6N^2 = 3M^2 + 2MN + 9MN + 6N^2

= M(3M + 2N) + 3N(3M + 2N) = (3M + 2N)(M + 3N)

Answer: 3M^2 + 11MN + 6N^2 = (3M + 2N)(M + 3N)
