Which expression is NOT equivalent to −38⋅(−4+12)? Drag this expression to the box.
lesya [120]

I had this question so here's the answer and explanation! :)

Answer:

The answer to your question is the first option :D

Step-by-step explanation:

Original expression

                                -3/8 (-4 + 1/2)

First option    -3/8 (-4)  + (3/8)(1/2)       This option is not equivalent because

                                                             they forgot the negative sign of the

                                                             second term.

Second option (-3/8)(-4) + (-3/8)(1/2)    This option is equivalent to the

                                                              original. Distributive property

Third option    (-3/2)(-3 1/2)                 This option is equivalent to the original

Fourth option  (-3/8)(-3) + (-3/8)(-1/2)  This option is equivalent to the original

HOPE THIS HELPS :)

Hey, there! For this question, we can just start by plugging in the known values. (f + g)(x) can be rewritten as (\frac{x}{2} - 3 + 3x^2 + x - 6)(x).

Combine like terms: (\frac{x}{2} + x - 3 - 6 + 3x^2)(x)

If you add x to \frac{x}{2}, x will become \frac{2x}{2}, which means that x/2 + x = 3/2x.

--> (\frac{3}{2}x - 9 + 3x^2)(x)

If you rearrange this, then your answer will be option b. Hope this helps.
