Note the squares...
13 is possible because it is a sum of two squares (integers) 9 + 4 .. use (0,3) & (2,0) ... get the square roots and place on different coordinate axes... for a simpler value.
but there is none for 15...
there is one for 18 ...
18 = 3^2 + 3^2 ... try (0,3) ,(3,0) , (3,6), (6,3).
Answer:
x =
Step-by-step explanation:
We have the equation: 3 + =
Move the constant (in this case the constant is 3) to the right side of the equation, changing its sign
= - 3
Calculate the difference.
=
Divide.
(when dividing two fractions, you can change it to a multiplication problem by switching the numerator and denominator of the divisor.)
So, we get the equation x which is .
