A 42-inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece
Karo-lina-s [1.5K]

Answer: 7 inches

Step-by-step explanation:

       If x is the first piece, and the second piece is twice as long, then the second piece is 2x.

        If the third piece is three times as long as the first piece, x, then the third piece is 3x.

       The 42-inch board must be equal to all 3 pieces, so we will set up an equation and solve for x.

42 = x + 2x + 3x

42 = 6x

42 = 6x

7 = x

              The first piece is 7 inches long.

Does anybody know this?Find the area of the regular polygon
sweet [91]

Answer:

<h2>2,268 square units</h2>

Step-by-step explanation:

Step 1

Find the area of 1 Triangle

To find this, we will use this formula:

A=\frac{1}{2} *B*H

Let's use the formula!

A=\frac{1}{2} *14*27\\=\frac{1}{2}* 378\\=189

<em>The area of 1 triangle is 189 square units</em>

<em></em>

Step 2

Find the area of the whole intire shape by multiplying the area of 1 triangle with the amount of sides.

There are 12 sides, so let's multiply 189 by 12

189x12=2268

<h2>Hence, the area of the regular polygon is 2,268 square units</h2>
