Answer:

345

7-\left(-19\right)-18+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187

7+19-18+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187

26-18+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187

8+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187

8-19+187-\left(-19\right)-18+\left(-19\right)+187

-11+187-\left(-19\right)-18+\left(-19\right)+187

176-\left(-19\right)-18+\left(-19\right)+187

195-18+\left(-19\right)+187

177+\left(-19\right)+187

177-19+187

158+187

Now, how many way he can do it? => half dollars = 0.5 => quarter dollars = 0.25 Possible ways: => 0.5 + 0.5 + 0.5 + 0.5 = 2 dollars (4 half dollars) => .25 + .25 + .25 +. 25 + .25 + .25 + .25 + .25 = 2 dollars (8 quarter dollars) => 0.5 + 0.5 + 0.25 + 0.25 + 0.25 + 0.25 = 2 dollars => 0.5 + 0.5 + 0.5 + 0.25 + 0.25 = 2 dollars => 0.5 + 0.25 + .25 + .25 + .25 + .25 + .25 = 2 dollars

Multiply the given polynomials. Answers should be simplified and written in standard form.
e-lub [12.9K]

Answer:

a² - 5a - 36

Step-by-step explanation:

(a - 9)(a + 4)

each term in the second factor is multiplied by each term in the first factor, that is

a(a + 4) - 9(a + 4) ← distribute parenthesis

= a² + 4a - 9a - 36 ← collect like terms

= a² - 5a - 36
