Is there supposed to be an attached image for us to see?
Answer:
in short, Yes they are always rational.
here's why...
E.g. suppose
and
are fractions, that means that a,b,c,d are all integers, and b and d are not zero. finding the sum the numerator, and denominator would also have to be integers. the denominator of the sum can't be zero since the denominators of the fractions were not zero, and would give
and since they are bound by addition (sum means addition) they must also be rational since eit would equal a bigger integer than initially had
Step-by-step explanation:
I think it would be ''(A) 5 cm on the map represents 50m in chicago''
I know it would be a ...it could also be (B)
but i know that its a for a fact
hope i helped ya
if not im very sorry
Answer:
B) x = 7, y = 4
Step-by-step explanation:
you can find the value of 'y' first by connecting the bases with another altitute measuring 4 units
you now have an isosceles triangle where each leg is 4 which makes the hypotenuse equal to 4
to find 'x', it is the sum of 3 and 4
