G is<span> the centroid it means that BG/FG=2 (G divides the median with this ratio)
3x+6/2x-1=2
3x+6=4x-2
x=8
then AG=26 then GE=13 so AE=39</span>
Answer:
27
Step-by-step explanation:
Given that :
Dimension of poster board = 1 yd by 1 yd
Dimension of each poster sign = 1/3 yd by 1/9 yd
Number of poster signs that can be cut :
Area of poster sign = 1/3 * 1/9 = 1/27 yard²
Area of poster board = 1 yard²
Number of poster signs that can be cut :
Area of poster board / area of poster sign
1 yard² ÷ (1/27) yard²
1 ÷ 1/27
1 * 27/1
= 27 poster signs
The value of 9−(−12) as an addition expression is 3.
<h3>What is a expression?</h3>
Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations.
In this case, the expression given is illustrated as:
-9 - (-12)
It's important to note that (-) × (-) = +
Therefore, -9 - (-12)
= - 9 + 12
= 3

Answer:
the correct option is B
Step-by-step explanation:
AC and AB are both radii of circle A
an equilateral triangle is one with all three sides the same length and angle.
from point A of circle A, a compass is use to bisect.
it works because the compasss width is not changed between drawing each side, guaranteeing they are all equal with the same length
using an object and a circular base
1
. Use any cylindrical object with a circular base, each side of the equilateral triangle will be as long as the radius (half the diameter) of the circular object.
2. Draw the first side. It should be exactly as long as the radius of the circular object – the distance halfway across. Make sure that it is perfectly straight!
If you have a ruler: simply measure the diameter of the object and draw a line that is half as long.
If you don't have a ruler: place the circular object onto a sheet of paper, then carefully trace the circumference with your pencil. Remove the object, and you should have a perfect circle. Use a straight edge to draw a line across the exact center of the circle: the point that is completely equidistant from any point around the circumference of the circle.
3. Trace another arc. Now, shift the circular object so that the edge touches the other end of the line segment. Make sure that the line segment runs through the exact center of the circle. Draw another quarter-arc that crosses the first arc at a point directly above the line segment. This point is the apex of your triangle.
4. Complete the triangle. Draw the remaining sides of the triangle: two more straight lines will connect the apex with the two open ends of the line segment.

Hello,
To answer your problem, use the Pythagorean Theorem for 2 right triangles and the Area of a Rectangle to find the Area of the Parallelogram.
All together:
A = 2(area of right triangle) + (area of rectangle)
A = 2[1/2*b*h] + [b*h]
To find the area of the parallelogram, I would be here for a while. Haha
