Step-by-step explanation:
x^2 + 8x + 0 = 0
Completing the square just means getting yourself a perfect square trinomial on the left side of your equation. It makes factoring easier for you. The steps are like this:
x² + 8x + 0 = 0 ... take the middle coefficient, 8, divide it by 2, and square it. Same process every time. Divide middle by two, square it. This gives you the "perfect square" of your equation. In this case, 8/2 = 4, and 4² = 16. So what you do is add 16 to BOTH sides of the equation.
x² + 8x + 16 = 16 ... factor the left side
(x + 4)(x + 4) = 16 ... notice that your two factors on the left are identical
(x + 4)² = 16 ... now we want to solve for x. Start by taking the square root of both sides
x + 4 = √16 ... √16 can give us two results: -4 and 4. So solve for both.
x + 4 = 4 x + 4 = -4 ... solve for x
x = 0, x = -8
<em>It is cut off so I do not know whether it is from least to greatest or greatest to least. </em>
If it is from <u>least to greatest</u>, then the answer is:
-2/3, -0.29, -0.27
If it is from <u>greatest to least</u>, then the answer is:
-0.27, -0.29, -2/3
-2/3 as a decimal is -0.66. This would put it at the lowest number in the group. Because these are negative numbers, you have to picture them as being on a number line-you cannot just look at the biggest integers. -0.66 is furthest down the number line, followed by -0.29, and finally -0.27 is closest to 0, making it the largest number in the group.
Answer:
In drawing an elevation drawing, there are four or five views of the sides of an object which may be displayed including the front, rear, and sides of the object
The elevation drawing is a scaled horizontal orthographic projection showing one side of an object to a plane vertical parallel to the object's sides so as to depict the appearance of the completed object appearance
The required elevation is included in the attached diagram

Answer: Use Fractions and Multiplication.
Step-by-step explanation:
To start, you need to find 1/6 of 12. The easiest way to do this is to multiply 12/1 by 1/6. The answer is 12/6, which simplifies to 2. Then, you do the same for 2/3: 12/1*2/3=24/3, which simplifies to 8. You then add the results to figure out how much has been eaten. 8+2=10
<span>Rational exponent are exponents written in the form of a fraction.
A rational power can be rewritten as a radical in the following way: the bottom of the rational exponent is the root, while the top of the rational exponent is the new exponent on the radical.
Example: X^(1/2)= </span>√X
