Answer:

5/8

Step-by-step explanation:

To find the slope, use the formula

m = (y2-y1)/(x2-x1)

= (2 - -3)/(6 - -2)

= (2+3)/(6+2)

= 5/8

Find the distance between the points (-1,-5) and (-10,7).

Paladinen [302]

Answer:

15 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (- 1, - 5) and (x₂, y₂ ) = (- 10, 7)

d = $\sqrt{(-10+1)^2+(7+5)^2}$

= $\sqrt{(-9)^2+12^2}$

= $\sqrt{81+144}$

= $\sqrt{225}$

= 15 units

Can anyone please help me find the length of X?

Alex_Xolod [135]

Solution:

Note that:

2(Perimeter of smaller triangle) = Perimeter of larger triangle

Using the perimeter of the smaller triangle, solve for x.

2(Perimeter of smaller triangle) = Perimeter of larger triangle
=> 2(3.5 + x + h) = 7 + 4 + 2h
=> 7 + 2x + 2h = 7 + 4 + 2h
=> 2x = 4
=> x = 2

The length of x is 2 units.

What is the area of this figure?

ludmilkaskok [199]

Answer:

$\large\boxed{\large\boxed{42 unit^2}}$

Explanation:

The figure is not a regular hexagon. It is an irregular hexagon.

Please, find attached the picture with the original question and the figure.

You can split the figure into two triangles and one rectangle.

The rectangle has dimensions: 7units × 4units, thus its area is 28 units².

Both the upper triangle and lower triangle have base 7 units and height 2 units.

Hence the area of each triangle is:

$area=(1/2)base\times height$

$area=(1/2)7units\times 2units = 7units^2$

Hence, the area of the hexagon is:

$28units^2+7units^2+7units^2=42units^2$
