Answer:

<h2>10+2x=4</h2>

first, by using inverse operations subtract 10 on both sides.

<h2>10-10+2x=4-10</h2>

4-10 is -6. whys the 6 negative? because the number takes the sign of the bigge number.

<h2>2x=-6</h2>

Divide by 2 to isolate x

<h2>2x÷2=-6÷2</h2>

In multiplication and division one negative sign stays and 2 negative signs cancel eachother but here theres only one negative sign so;

~~~~~~~~~~~~~~~~

<h2>X=-3</h2>

Sergio [31]

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to find how many terms are in \pmb{10y^2-3y+8}.

\triangle~\fbox{\bf{KEY:}}

  • A term is a thing that's added or subtracted.

So let's compute the number of terms in this expression.

The first term is \pmb{10y^2}.

Is anything added or subtracted from 10y²?

Sure! \pmb{-3y} is subtracted from 10y².

Also, 8 is added to -3y.

Thus, this expression has 3 terms.

Hope it helps you out! :D
