Question: x+y=y+x verify

x=5/7,y=-3/2

L.C.M=7^2=14

(-21)+10/14=-11/14

-3/2+10/7

-21+10/14=11/14

X+Y=Y+X=-11/14=-11/14 this is verify

Meghna Thapar 5 years, 6 months ago

A rhombus is a polygon having 4 equal sides in which both the opposite sides are parallel, and opposite angles are equal. Examples: Input: d1 = 2 and d2 = 4 Output: The area of rhombus with diagonals 2 and 4 is 4. The perimeter of rhombus with diagonals 2 and 4 is 8. Area of a Rhombus Formula - Perimeter and Area of Rhombus. ... Since the diagonals of a rhombus bisect each other at 90°, we can calculate the height and the base of one of these triangles and multiply the result by two to get the area of the rhombus.

Perimeter of triangle =sum of all sides If triangle's side 1 is 2cm. side2 is 4cm. And side 3is 5cm. So it's perimeter is like this :-> We know, perimeter of the triangle is sum of all sides of triangle Length if side 1= 2cm. Length of side 2= 4cm. Length of side 3=5cm. Perimeter= (2+4+5)cm. =11cm. But when we have to find the perimeter of equilateral triangle so,we have the formula like 3×sides Okk are you fine with this answer?

The area of a triangle is half the product of its base and height. The area A of an equilateral triangle of side length s cm can be calculated using the formula A = √3⁄4 s2. The formula for finding the perimeter of a triangle. For a triangle with sides a, b and c, the perimeter P is defined as: P = a + b + c. What this formula means in simpler terms is that to find the perimeter of a triangle, you just add together the lengths of each of its 3 sides.

What is the squre root

Meghna Thapar 5 years, 6 months ago

A square root of a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4. The symbol is √ which always means the positive square root. A negative square root is one of two square roots of a positive number. For the number 25, its negative square root is -5 because (-5)^2 = 25. We can solve certain equations by finding the square root of a number.

Sia ? 4 years, 7 months ago

Given that
Let us assume that the lowered temperature as negative,
Initial temperature = 40^oC
Change in temperature per hour = -5^oC
Change in temperature after 10 hours = (-5) × 10 = -50^oC
{tex}\therefore{/tex} The final room temperature after 10 hours of freezing process = 40oC + (-50^oC)
= -10^oC
The room temperature 10 hours after the process begins= -10^oC
