Answer:

60 feet of fencing

Step-by-step explanation:

Let x feet be the width of the garden plot, then 2x feet is the length of  the garden plot.

The area of the garden plot is

A=x\cdot 2x\\ \\200=2x^2\\ \\100=x^2\\ \\x=10\ feet\\ \\2x=20\ feet

Find the perimeter of the rectangular garden plot:

P=x+2x+x+2x\\ \\=10+20+10+20\\ \\=60\ feet

Answer:

The length of the fence that Lebron requires is:

  • <u>60 feet</u>.

Step-by-step explanation:

Since the land is mentioned to be rectangular twice as long as it is wide, it must be calculated taking into account the given area of ​​200 square feet, which can be done using the following formula:

  • Area = Width (W) * Length (L)

The formula is replaced based on a single variable:

  • 200 sq. ft = W * 2W (Since it is mentioned that the length is twice the width).

Performing the multiplication we obtain:

  • 200 sq. ft = 2W ^ 2

Pass the number you are multiplying to divide on the other side of equality:

  • 200 sq. ft / 2 = W ^ 2

To eliminate the square, the square root is taken from both sides of the equality:

  • root (200 sq. ft / 2) = W
  • W = root (200 sq. Ft / 2)
  • <u>W = 10 feet</u>

Since the length is twice the width then:

  • L = W * 2 = 10 * 2 = <u>20 feet </u>

Having the dimensions, the Perimeter can be calculated, which is the length that surrounds the terrain, which is calculated for rectangles such as:

  • <u>Ground perimeter = 2 * width + 2 * length. </u>

By replacing you get:

  • Ground perimeter = 2 * 10 feet + 2 * 20 feet.
  • Ground perimeter = 20 feet + 40 feet.
  • <u>Ground perimeter = 60 feet</u>.

For the first question it is 2.

2 x 2 = 4

5 x 2 = 10

4 + 10 - 14 = 0

The second question is -2

-2 x -2 = 4

5 x -2 = -10

4 + -10 + 6 = 0

Hope this helps

3. Multiply (2x - 3) by (x2 - 2x + 1)
Roman55 [17]

Answer:

<h2><u>B.</u></h2>

2x^3 - 7x^2 + 8x -3

Step-by-step explanation:

To multiply a binomial (2 terms) by a trinomial (3 terms):

Multiply the first term of the binomial by the each term of the trinomial.

Multiply the second term of the binomial by each term of the trinomial.

Combine the expressions and simplify.

(2x-3)*(x^2-2x+1)

(2x * x^2) + (2x * -2x) + (2x * 1)

(2x^3) + (-4x^2) + (2x)

(2x-3) * (x^2-2x+1)

(-3 * x^2) + (-3 * -2x) + (-3 * 1)

(-3x^2) + (6x) + (-3)

[2x^3 + -4x^2 + 2x] + [-3x^2 + 6x + -3]

2x^3 - 7x^2 + 8x -3
