Steven is cutting an 11 ft piece of lumber into three pieces to build a triangular garden. Which diagram shows a way in which he can cut the wood to create three pieces that can form a triangle? A piece of wood is cut into 3 pieces. The pieces are: 2 feet, 2 feet, and 7 feet.
A piece of wood is cut into 3 pieces. The pieces are: 1 foot, 4 feet, 6 feet.
A piece of wood is cut into 3 pieces. The pieces are: 3 feet, 2 feet, and 6 feet.
A piece of wood is cut into 3 pieces. The pieces are: 3 feet, 4 feet, 4 feet.

The answer is D) 3ft, 4ft, 4ft.

Step-by-step explanation:

You can find the answer by adding two of the three measures, and if the answer is greater than the third measure then you will be able to make a triangle. Be sure to check each of the measures just in case.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
