stiks02 [169]

Answer:

<h2>35x - 35y + 21</h2>

solution,

0.5(20x - 50y + 36) - 0.25( - 100x + 40y - 12) \\  = 10x - 25y + 18  + 25x - 10y + 3 \\

Combine the like terms:

= 10x + 25x - 25y - 10y + 18 + 3 \\

Simplify:

35x - 35y + 21

Hope this helps...

Good luck on your assignment...

Find a polynomial function of the lowest degree, with real coefficients, with the given roots.
makvit [3.9K]

Answer:

D

Step-by-step explanation:

Roots into factors:

x = -4 ----> (x + 4)

x = i -----> (x - i)

x = 5 -----> (x - 5)

(x + i)(x - 4)(x + 5)

(x - i)(x² - 4x + 5x - 20)

(x - i)(x² + x - 20)

x³ + x² - 20x - (ix² + ix - 20i)

x³ + (1 - i)x² - (20 + i)x + 20i
