Natural number are basically " counting numbers ". They have no decimals, no fractions, and no negative numbers. It is debated whether 0 is included.

so ur natural numbers less then 3 are {1,2 }...not 100% sure if u include 0. I do not think u do.

explain why division by zero is not allowed.Don't give an exact definition from another source.Use pictures or real-life example

Division by zero simply would work because you cannot divid something by zero, it would be the same as not dividing it at all. take a birthday cake, if you divide it by zero, u didn’t cut it at all

Find the coordinates of the circumcenter of △PQR with vertices P(−2,5), Q(4,1), and R(−2,−3).

mel-nik [20]

Answer: (1/3,2)

Step-by-step explanation:

Let O(x,y) be the circumference of the triangle PQR,

Thus, by the property of circumcenter all the vertices of the triangle are at same distance from this circumcenter.

Thus, PO = QO

By the distance formula,

$(x+2)^2+(y-5)^2 = (x-4)^2+(y-1)^2$

$\impliesx^2+ 4x + 4 + y^2+ 25 - 10 y = x^2+16 - 8 x + y^2+1 - 2y$

$\implies 4x + 4 + 25 - 10 y = 16 - 8 x + 1 - 2y$

$\implies 4x +8x-10y+2y = 16 + 1 -25-4$

$\implies 12x - 8y = 17 - 29$

$\implies 12 x - 8 y = - 12$ ---------(1)

Similarly, QO = RO

$\implies (x-4)^2 + (y-1)^2 = (x+2)^2+(y+3)^2$

$\implies x^2 + 16 - 8x + y^2+ 1 - 2y = x^2+ 4 + 4 x +y^2+ 9 + 6 y$

$\implies 16 - 8x + 1 - 2y = 4 + 4 x + 9 + 6 y$

$\implies - 8x -4x-2y-6y=4+9-16-1$

$\implies -12 x - 8 y = 13 - 17$

$\implies 12 x + 8 y = 4$ ------------(2)

By adding equation (1) and (2),

24 x = - 8

x = 1/3

By putting this value in equation (1),

We get,

Thus, 4 - 8 y = -12

8 y = 16

y = 2

Help is very much needed :)

ioda

Answer:

6

Step-by-step explanation:

10/5 ×/3 multiply 10×3 and than divide by 5

or another way start with multiplying 5 and n equaling 5n=

than 10× 3= 30 so you're left with 5n=30 divied 30 by 5 equalling 6

so x=6

Multiply (x-3)(4x+2) using the distributive property.

asambeis [7]

$\text{The distributive property:}\ (a+b)(c+d)=ac+ad+bc+bd\\\\(x-3)(4x+2)=(x)(4x)+(x)(2)-(3)(4x)-(3)(2)\\\\=4x^2+2x-12x-6=4x^2-10x-6$
