Hey please help, thank you!!

D

Step-by-step explanation:

So we have the equation:

And we want to find out which of the answer choices is not equivalent.

Thus, let's go through each of the choices.

A)

We have:

This is correct.

Our original equation can be written as:

And if we multiply straight across:

We'll get choice A. So choice A is correct.

B)

We have:

This is also correct.

From our original equation:

If we multiply the first term together:

We'll get choice B. So, choice B is correct.

C)

We have:

This is correct as well.

If we reduce 1/2 to decimal form and add the operations within the parentheses in the original equation, we will get:

So, C is also correct.

D)

We have:

Note that this is not correct.

This attempted to use the distributive property. However, the distribute property does not work for multiplication. For instance:

However:

So, choice D is not equivalent.

So choice D is our answer :)

If we evaluate it, we will get 30, in contrast to the 60 of the others.

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
