For this case we must factor the following expression:
To factor, we must find two numbers that when added together give -7 and when multiplied by -10.
It is observed that there are not two whole numbers that comply with the aforementioned.
Thus, the following equation applies:
Where:
We replace:
So, the roots are:
Answer:
Answer:
a). cosA = 4/5
b).
Answer:
Step-by-step explanation:
Alright, lets get started.
The part of the diagonals are given as 0.9 m and 1.2 m.
The diagonals of rhombus intersect each other.
Hence the length of diagonals will be : and
The formula of area of rhombus is : where p and q are the length of diagonals.
So plugging the values of diagonals in formula, the area will be :
Area =
Area =
Area = ................. Answer
Hope it will help :)
The diagonals of the Rhombus= d1 & d2=6cm and 8cm
Let the Side=a
As we know that in a Rhombus
we know that in a Rhombus
Perimeter of the rectangle is 20cm.
