The length would be 14.
because 4 less than 3 times the width and the perimeter being 40 you would divide 40 by 2 and you get 20.
4 less than 20 would be 16 but that would make the length equal to the width, therefore, your answer is 14.

Lady bird [3.3K]

Answer:

Expression representing number of text messages sent on Tuesday = 2x , where x = text messages sent on Monday

Step-by-step explanation:

Let number of messages sent on Monday = x

So, number if messages sent on Tuesday = 2 times x = 2x

Number of texts sent on Wednesday = 12 more than texts sent on Tuesday = 2x + 12

Number of texts sent on Thursday = Half the texts sent on Wednesday = 1/2 (2x + 12) = x + 6

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.
