Step-by-step explanation:

<h3>Given</h3>
  • Side 1: 3x² - 2x - 1
  • Side 2: 9x + 2x² - 3
  • Perimeter:  5x³ + 4x² - x - 3
<h3>Part A</h3>

Sum of side lengths 1 and 2

  • 3x² - 2x - 1 + 9x + 2x² - 3 =
  • 5x² + 7x - 4
<h3>Part B</h3>

The perimeter is the sum of all three sides.

<u>The length of the third side is</u>

  • P - (side 1 + side 2) =
  • 5x³ + 4x² - x - 3 - (5x² + 7x - 4) =
  • 5x³ + 4x² - x - 3 - 5x² - 7x + 4 =
  • 5x³ - x² - 8x + 1

Part A - addition

Part B - subtraction

The diameters of a circle is 7m. Find its area to the nearest tenth?? Help please
Lady bird [3.3K]

Area =\pi r^{2}

The diameter is double the length of the radius

7 ÷ 2 = 3.5

3.5 × 3.5 = 12.25

12.25\pi = 38.4845100064751

38.4845100064751 rounded to the nearest tenth is 38.5

Answer:

Find the area by multiplying the base by the height. From the problem, the length (base) of the rectangle is 5 units. The height of the rectangle is

3\frac{1}{2}

inches. Multiply to find the area.

5 \times  3 \frac{1}{2}  = 17 \frac{1}{2}

The area of the rectangle is 17 1/2 units squared. The answer you provided is correct!
