So the length is 4*28=112mm
The width would be calculated like this:
you draw an equilateral triangle in the middle with sides or 2r(56mm). The based on pythagorean theorem u know that
h=rad(56^2-28^2)=48.497
28+28+h=104.497
The area would be S=l*w which is 11703.7113mm
When 4•12 is compared to 8•6, it can be concluded that →
4 • 12 = 8 • 6.
<h3>What is Comparison in Mathematics?</h3>
Comparison in mathematics is used to compare two numbers or expressions in order to find which number or expression is greater or small.
Following symbols are used for comparison →
> (greater than)
< (less than)
≥ (greater than or equal to)
≤ (less than or equal to)
= (equal to)
Given is the following statement - 4•12 compared to 8•6.
In order to compare both expressions, first we will have to simplify them-
4 • 12 = 48
8 • 6 = 48
Now, if we compare both the expressions, we can conclude that both are equal.
Therefore, when 4•12 is compared to 8•6, it can be concluded that →
4 • 12 = 8 • 6.

Answer:
- m = 4/3; b = -4
- m = 3; b = -6
Step-by-step explanation:
In each case, <em>solve for y</em>. You do this by getting the y-term by itself, then dividing by the coefficient of y.
<h3>1.</h3>
-3y = -4x +12 . . . . . subtract 4x
y = 4/3x -4 . . . . . . . divide by -3
The slope is 4/3; the y-intercept is -4.
__
<h3>2.</h3>
y = 3x -6 . . . . . . divide by 2
The slope is 3; the y-intercept is -6.

<em>Additional comment</em>
Whatever you do to one side of the equation, you must also do to the other side. When we say "subtract 4x", that means 4x is subtracted from both sides of the equation. The reason for doing that in the first equation is to eliminate the 4x term from the left side.
(Sometimes, you may see operations described as "move ...". There is no property of equality called "move." There are <em>addition</em>, <em>subtraction</em>, <em>multiplication</em>, <em>division</em>, and <em>substitution</em> properties of equality. Any equation solving process will make use of one or more of these.)
Answer:
50 degrees
Step-by-step explanation:
because it is a parallelogram, angle B = angle D, and angle C = angle A
that means we have 130(2) = 260 degrees that we know.
the total interior angles of a parallelogram = 360
360 - 260 = 100 degrees left. BUT because those are the total amount of angles left, those are angles A and C combined, so you have to divide 100 in half to get the angle A/ angle DAB
100/2 = 50 degrees. hope this helps! leave a question if you are still confused.
