Answer:
<u>The correct answer is D. -5 +/- i√2</u>
Step-by-step explanation:
Let's solve for x, the equation given to us, this way, using the quadratic formula:
x = (- b +/- √b² - 4ac)/2a
Replacing with the real values, we have:
x = (-10 +/- √10² - 4 * 1 * 27)/2
x = (-10 +/- √100 -108)/2
x = (-10 +/- √-8)/2
x = (-10 +/- √-1 * 4 * 2)/2 Let's recall that √-1 = i
x = (-10 +/- 2i√2)/2
x = 2 (-5 +/- i√2)/2 (Dividing by 2 both the numerator and the denominator)
<u>x₁ = -5 + i√2</u>
<u>x₂ = -5 - i√2</u>
<u>The correct answer is D. -5 +/- i√2</u>
Answer:
Quotient = x² + x + 3
Reminder = 10
Step-by-step explanation:
We need to divide , x³ - 4x² - 2x - 5 by x - 5
x - 5) x³ - 4x² - 2x - 5 ( x² + x + 3
- x³ -(+)5 x²
_______________
0 + x² - 2x - 5
x² -5x

Your correct and final answer is D. Add $7.79 to $3.95. Subtract the sum from $18.46. Divide this number by 4. Have a nice day!! :)
Answer:0 ways
Step-by-step explanation:
1. The area is 1.875 meters², or 1 7/8 as a fraction because 2.5 (2 1/2) times .75 (3/4) = 1.875 (1 7/8).
2. The mural is 1.687 meters², or 1 687/1000 as a fraction because 2.25 (2 1/4) times .75 (3/4) = 1.687.
