Does a rhombus have perpendicular line segments
Answers
Answer:
A rhombus is a geometric figure that lies in a plane. It is defined as a quadrilateral all of whose sides are congruent. It is a special type of parallelogram, and its properties (aside from those properties of parallelograms) include:
Its diagonals divide the figure into 4 congruent triangles.
Its diagonals are perpendicular bisectors of eachother.
If all of a rhombus' angles are right angles, then the rhombus is a square.
Answer:yes it does have perpendicular lines

-2+y/10=-6
Answers
Answer:
y = -58
Step-by-step explanation:
You have to isolate the y:
-2+y/10 = -6
First step, multiply both sides by 10:
-2+y = -60
Second step, add 2 on both sides:
y = -58
It's done!
Answer:
-2=-40/10=-6
Step-by-step explanation:
-2/10 alone is -0.2.
Using PEMDAS your problem should look more like, (-2)+((y)÷10)=
Using this new formula let's start plugging in numbers.
(-2)+((0)÷10)= -2
(-2)+((-1)÷10)= -2.1
(-2)+((-2)÷10)= -2.2
Now there is a pattern, you can calculate or just keep moving up the latter until you reach the desired sum.
After finding the plug-in use PEMDAS to solve.
(-2)+((-40)÷10)=
((-40)÷10)= -4
-4+-2=-6.
So (-2)+((-40)÷10)= -6

where a and b are integers.
Answers
Answer:
as the diagram is not provided by you
Step-by-step explanation:
proper an answer cannot be written if the three circles touch Each Other as well as the the sides of the rectangle it means that rectangles length and breadth are made by attaching to circles together which means that length and breadth of the rectangle are equal therefore length is equal to diameter of one circle into two that is 8 therefore length and breadth of the rectangle are 8 each other for exact area of rectangle is 8 x 8 = 64

There are several methods to solve equations of the type AX = XB. These type of equations occur in domains like robotics, for which solutions have been proposed like the Tsai and Lenz method [IEEE 1987], for example. 1) I feel solving the equation XA = XB is not the same as solving the known form AX = XB. Am I right? 2) Neither can it be solved like the Sylvester equation, because even that requires AX+XB=CAX+XB=C form. What i have is XA=XBXA=XB, a redundant set of equations. That is,
A1.XA2.XAn.X=X.B1=X.B2⋮=X.BnA1.X=X.B1A2.X=X.B2⋮An.X=X.Bn
If i am correct, these could be rewritten into another form like AX=BXAX=BX. Should i rewrite the equation and try to solve this problem using any other existing methods?
