One integer is 1/3 times another. The sum of their squares is 90. What are the two integer?
beks73 [17]
<h2>Answer:</h2>

Hence, the two integers could be:

                   3 and 9

                        0R

                   -3 and -9

<h2>Step-by-step explanation:</h2>

Let the two integers be denoted by a and b.

It is given that:

One integer is 1/3 times another.

i.e. let

a=\dfrac{1}{3}b

i.e.

b=3a

Also,

The sum of their squares is 90.

i.e.

a^2+b^2=90\\\\i.e.\\\\a^2+(3a)^2=90\\\\i.e.\\\\a^2+9a^2=90\\\\i.e.\\\\10a^2=90\\\\i.e.\\\\a^2=9\\\\i.e.\\\\a=\pm 3

Hence, when a=3 we have:

b=9

and when,

a=-3

then b=-9
