The sum of a rational number and an even integer is rational. A) Always True B) Sometimes True C) Usually True D) Never True
SOVA2 [1]
I think that the sum will always be a rational number
let's prove that


<span>any rational number can be represented as a/b where a and b are integers and b≠0

</span>and an integer is the counting numbers plus their negatives and 0
so like -4,-3,-2,-1,0,1,2,3,4....

<span>so, 2 rational numbers can be represented as

</span>a/b and c/d (where a,b,c,d are all integers and b≠0 and d≠0)

their sum is
a/b+c/d=
ad/bd+bc/bd=
(ad+bc)/bd

1. the numerator and denominator will be integers
2. that the denominator does not equal 0

alright
1.
we started with that they are all integers
ab+bc=?
if we multiply any 2 integers, we get an integer
<span>like 3*4=12 or -3*4=-12 or -3*-4=12, etc.
</span>even 0*4=0, that's an integer
the sum of any 2 integers is an integer
like 4+3=7, 3+(-4)=-1, 3+0=3, etc.
so we have established that the numerator is an integer

now the denominator
that is just a product of 2 integers so it is an integer


<span>2. we originally defined that b≠0 and d≠0 so we're good

</span>therefore, the sum of any 2 rational numbers will always be a rational number <span>is the correct answer.</span>

\huge \mathfrak \blue{Solution \:  - }

The formula for area of triangle is -

\frac{1}{2}   \times base \times height

________________________________

So, the area of first triangle =

\frac{1}{2}  \times base \:  \times height

\frac{1}{2}  \times 4  \times 3

=  \pink{6  \: units}

________________________________

Area of second triangle =

\frac{1}{2 }  \times base \times height

\frac{1}{2}  \times 4 \times 6

=  \pink {12 \:  units}

________________________________

Area of second triangle - Area of first triangle

= 12 - 6

= 6

\sf \underline\purple{The \: area \: increases \: by \: 6 \: square \: units.}
