explanation;

Solution for 2x+1=5x-5 equation

Simplifying

2x + 1 = 5x + -5

Reorder the terms:

1 + 2x = 5x + -5

Reorder the terms:

1 + 2x = -5 + 5x

Solving

1 + 2x = -5 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

1 + 2x + -5x = -5 + 5x + -5x

Combine like terms: 2x + -5x = -3x

1 + -3x = -5 + 5x + -5x

Combine like terms: 5x + -5x = 0

1 + -3x = -5 + 0

1 + -3x = -5

Add '-1' to each side of the equation.

1 + -1 + -3x = -5 + -1

Combine like terms: 1 + -1 = 0

0 + -3x = -5 + -1

-3x = -5 + -1

Combine like terms: -5 + -1 = -6

-3x = -6

Divide each side by '-3'.

x = 2

Simplifying

x = 2

Find the side length of the equilateral triangle whose area is the square root of 3 cm2

Alla [95]

Here, Given

Area of Equilateral triangle = 3cm2

therefore, we know;

Area of Equilateral triangle =( $\sqrt{3}$ ÷4)× $a^{2}$

so,

3 =( $\sqrt{3}$ ÷4)× $a^{2}$

3÷( $\sqrt{3}$ ÷4) = $a^{2}$

2.63 cm = a .

The area of an equilateral triangle is the area covered by an equilateral triangle on a two-dimensional plane. An equilateral triangle is a triangle with all sides equal and all angles at 60 degrees. The area of the shape is the number of unit squares that fit inside.

Here, "unit" refers to 1, and a unit square is a square with one side. Alternatively, the area of an equilateral triangle is the total amount of space it surrounds in a two-dimensional plane.
