Answer:

Step-by-step explanation:

a.18/-3 = (-6)

b. -5/-1 = 5

c. 24/-6 = (-4)

d. -10/-1 = 10

e. -25/5 =(-5)

f. 8/-2 = (-4)

In multiplication and division, if there are are odd number of negative signs, the result will have negative sign.

If there are even number of negative signs, the the result will have positive sign

You design a tree house using a coordinate plane in which the coordinates are measured in feet. The vertices of the floor are (-

Nikitich [7]

Answer:

Perimeter = 28 yards

Area = 49 square yards.

Step-by-step explanation:

Distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Let as consider the vertices of the floor are A(-2,-3), B(-2,4), C(5,4) and D(5,-3).

Using distance formula, we get

$AB=\sqrt{(-2-(-2))^2+(4-(-3))^2}=\sqrt{(-2+2)^2+(4+3)^2}=\sqrt{0+7}^2=7$

Similarly,

$BC=\sqrt{(5-(-2))^2+(4-4)^2}=7$

$CD=\sqrt{(5-5)^2+(4-(-3))^2}=7$

$AD=\sqrt{(5-(-2))^2+(-3-(-3))^2}=7$

It is conclude that, $AB=BC=CD=AD$ .

From the given points it is clear that all sides lie on either vertical or horizontal lines.

Since all sides are equal, and adjacent sides are perpendicular, therefore, the base is a square with edge 7 yards.

Perimeter of square floor is

$P=4a=4(7)=28\text{ yards}$

Area of square floor is

$A=a^2=7^2=49\text{ sq. yards}$

Therefore, the perimeter is 28 yards and the area is 49 square yards.

I'll help out a bit:

Step-by-step explanation:

So ANY number in a square root is irrational(Non-terminating and no pattern)

Pi is also irrational

But ANY number that can be expressed as a fraction is rational(Also Whole numbers, natural numbers, etc.)

Hope this helps!
