Answer:

-7x^2-14

Step-by-step explanation:

First, remove the parenthesis.  Remember to distribute the negatives properly!

(-2x^2+x+1)-(x^2-x+7)-(4x^2+2x+8)\\-2x^2+x+1-x^2+x-7-4x^2-2x-8

Next, rearrange the order of the numbers so it's easy to see the like terms.  Put the squared x's together, x's together, etc.  <em>This step is optional but helpful.</em>

-2x^2-x^2-4x^2+x+x-2x+1-7-8

Next, combine like terms.

-7x^2+0x-14\\-7x^2-14

Leave a note in the comments if you need me to elaborate on any steps.

4(v+7) = -6(3v-4) +8v<br>​
xxTIMURxx [149]

Answer:

v=−27

Step-by-step explanation:

Since v is on the right side of the equation, switch the sides so it is on the left side of the equation.

−6(3v−4)+8v=4(v+7)

Simplify −6(3v−4)+8v

−10v+24=4(v+7)

Simplify 4(v+7).

−10v+24=4v+28

Move all terms containing v to the left side of the equation.

−14v+24=28

Move all terms not containing v to the right side of the equation.

−14v=4

Divide each term by −14 and simplify.

v=−27

The result can be shown in multiple forms.

Exact Form:

v=−27
