Answer:

$\sqrt{29}$

Step-by-step explanation:

using the distance formula

d = √(x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 2, - 3) and (x₂, y₂ ) = (- 4, 2)

d = $\sqrt{(-4+2)^2+(2+3)^2}$ = $\sqrt{4+25}$ = $\sqrt{29}$ ← in exact form

A rancher has 2 comma 200 feet of fencing to enclose a rectangular pig pen. However, one side of the pen lies along a river and

DiKsa [7]

Answer:

$A = 2200x - 2x^2$

Step-by-step explanation:

Let's x be the length of the side that is NOT the same as the side along the river (or in opposite). From the fencing perimeter of 2200ft we can calculate the other side y of the rectangular:

y = 2200 - 2x

The area A of the pen would be the product of the 2 sides

$A = xy = x(2200 - 2x) = 2200x - 2x^2$

Answer:

$\text{B. }26}$

Step-by-step explanation:

Since $\overline{PN}$ and $\overline{PQ}$ are equal, we can set them equal to each other:

$7x+5=10x-4,\\9=3x,\\x=3$

Substitute $x=3$ to solve for $\overline{PQ}$ :

$\overline{PQ}=10(3)-4=\boxed{\text{B. }26}}$

Lalasa and yasmin are designing a triangular banner to hang in the school gymnasiums. They first draw the design on paper. The t

jasenka [17]

The triangle on paper is 5 inches wide by 7 inches high.

If 1 inch on paper is equal to 1.5 feet on paper, then you need to multiply all dimensions by 18 because 1.5 feet is equal to 18 inches and you are getting 18 inches on the real banner for every inch on the paper banner. 

5 * 18 = 90 inches from the base of the rear triangle.
7 * 18 = 125 inches for the height of the rear triangle. 
The area of the paper triangle will be 5 * 7 / 2 = 35/2 square inches.
The area of the rear triangle will be 90 * 125 / 2 = 5625 square inches. 

regarding feet:

The base of the real banner will be 125/12 = 10.41666666....... feet.
the height of the real banner will be 90 / 12 = 7.5 feet.
the area of the real banner will be 5625 / 12^1 = 5625 / 144 = 39.0625 square feet.
