alina1380 [7]

Answer:

N = \{1,2,3,4,5,6,.....\}

Step-by-step explanation:

Required

Determine the sets of natural number

Represent this set with letter N

From definition of natural numbers, they are integer numbers starting from 1;

In other words: 1,2,3,4,5, and so on.

To represent this as a set of N, we have

N = \{1,2,3,4,5,6,.....\}

<em>The ..... means that the counting still continues</em>

One number is 7 more than another. The difference between their squares is 161. What are the numbers?
olga nikolaevna [1]
Let's say the numbers are "a" and "b"

now, we know one of them is 7 more than the other, so hmmm let's say "b" is 7 more than "a", so b = a + 7

the difference of their squares is 161, alrite

\bf a^2-b^2=161\qquad b=a+7\implies a^2-(a+7)^2=161&#10;\\\\\\&#10;a^2-(a^2+14a+49)=161\implies \underline{a^2-a^2}-14a-49=161&#10;\\\\\\&#10;-14a-49=161\implies -49-161=14a\implies -210=14a&#10;\\\\\\&#10;\cfrac{-210}{14}=a

and surey you know how much that is

now, what's "b"? well, b = a + 7
