(-2x^2 + wx - 4) - (x^2 + 5x + 6) = -3x^2 - 10 what is the value of w? ?

(-2x² + wx - 4) - (x² + 5x + 6) = -3x² - 10    Distribute/multiply - into (x² + 5x + 6)

-2x² + wx - 4 - x² - 5x - 6 = -3x² - 10      Combine like terms

-3x² + wx - 5x - 10 = -3x² - 10         Add 10 on both sides

-3x² + wx - 5x = -3x²               Add 3x² on both sides

wx - 5x = 0          Add 5x on both sides

wx = 5x        Divide x on both sides

w = 5

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
