Mathematics

uranmaximum [27]3 years ago
7 0

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.

Verdich [7]

Answer:

b = $4000

Step-by-step explanation:

Let b represent the bonus amount.

Then the bonus, b, less the three deductions, is represented by

b - 0.30b - 0.30b - 025b, and this comes to $600.  Find the value of b.

b - 0.85b = $600, or

0.15b = $600

Then b = $4000
