Hey there!

It's given to subtract (3x² + 7x - 9) from (8x² - 4x + 1). So ⇨

(8x² - 4x + 1) - (3x² + 7x - 9)

= 8x² - 4x + 1 - 3x² - 7x + 9

= 8x² - 3x² - 4x - 7x + 1 + 9

= <u>5x² - 11x + 10</u>

Hope it helps ya!

Answer:

  A) $157,555

Step-by-step explanation:

The sum of assets is ...

  house + 2 cars = $280,000 +5,200 +15,600 = $300,800

The sum of liabilities is ...

  mortgage +car loan +credit card +wedding

  = $113,545 +9,200 +2,300 +18,200 = $143,245

The family's net worth is the difference between assets and liabilities:

  $300,800 -143,245 = $157,555
