If the given expression is simplified we get a. -4x² - 3x + 2.
Explanation:
- The numerator has three terms while the denominator only has one term. We divide the numerator terms each separately with the denominator term.
- So 8x³ + 6x² - 4x / -2x becomes (8x³ / -2x) + (6x² / -2x) + (- 4x/ -2x).
- The simplification of the first term; 8 / -2 = -4, x³ / x = x². So the first term is -4x².
- The simplification of the second term; 6 / -2 = -3, x² / x = x. So the second term is -3x.
- The simplification of the third term; -4 / -2 = 2, x / x = 1. So the third term is 2.
- Adding all the terms we get -4x² - 3x + 2. This is the option a.
<span>The z for $38.60 = (38.60 - 45)/16 = -0.4
</span>
<span>The percent of area associated with $38.60 = P(z < -0.4) = 0.34458 =34.46%
</span>
<span>The z for $57.80 = (57.8 - 45)/16 = 0.8.
</span>
<span>The percent of area associated with $57.80 = P(z < 0.8) = 0.78814 = 78.81%
</span><span>the percent of his expenses between $38.60 and $57.80 is (78.81 - 34.46) = 44.35%</span>
Answer:
Step-by-step explanation:
the answer is C
The least common multiple between those following numbers is C. 90.
Not really, If you use the Pythagorean theorem on all problems related to distance.. You won't always be able to solve it. It depends on the numbers.
So, false.
