-4x=-x2+12 should be written <span>-4x=-x^2+12, with " ^ " representing exponentiation.
You are to invent a table of x values and find the difference between -4x and -x^ 2+12. The smaller the difference, the closer you are to finding the correct root, x.
To get you started:
x -4x x^2+12 difference
--- ------------ ---------------- --------------
2 -8 16 24 (pretty bad!)
-4 16 28 12 (better)
-10 40 112 72 (much worse)
To answer this problem correctly, you must present such a table, even tho' it'd be faster to use the quadratic formula (or some other method) to find x.

The answer is choice A.
One line goes through (0,6) and (4,0); the equation of this line is 3x+2y = 12. The inequality 3x+2y < 12 means we shade below the boundary line which is a dashed line.
The equation 2x+y < 10 means we graph out 2x+y = 10 which goes through (0,10) and (5,0). The shading is also below the dashed boundary line. The shading is a bit off since the region above 3x+2y = 12 should not be shaded in. Also the boundary lines should be dashed lines.
1. Approximate the measure of your angle. Angles can be categorized in three ways: acute, obtuse, and right. Acute angles are less than 90 degrees, obtuse angles are greater than 90 degrees, and right angles are exactly 90 degrees.
2. Place the origin over the center point, or vertex, of the angle you want to measure. The small hole in the middle of the protractor is the origin. Put the vertex of the angle with the center of the cross in the origin.
3. Rotate the protractor to line up one leg of the angle with the baseline. Maintain the vertex of the angle in the origin and rotate the protractor so that one of the legs of the angle falls on the baseline of the protractor.<span>The baseline is even to the edge, but is not the flat edge of the protractor. It is lined up with the center of the origin and the line projects to the start of the scale on either side.
</span>4. Follow the opposite leg of the angle up to the measurements on the protractor's arc. If the line does not pass through the protractor’s arc, make the angle's line longer until it does. You can align the edge of a piece of paper with the angle’s leg to pass beyond the edge of the protractor, continuing the line of the angle. The number the line passes through is the angle's measurement in degrees. <span><span>

Answer:
Step-by-step explanation:
62.82 cm
Step-by-step explanation:
the formula of circumference of circle is 2 Pi R
so, 2 * 22/7 * 10 cm = 62.82 cm
