Answer:
see explanation
Step-by-step explanation:
Given
, 
Factor the denominators of both fractions
, 
The lowest common denominator of both fractions is (a + 4)(a + 5)(a + 7)
Multiply numerator/denominator of first fraction by (a + 7)
Multiply numerator/denominator of second fraction by (a + 5 )
, 
, then
, 
Answer:
The third option, a rational number
like 1/5 + 2.5 is still rational (but neither irrational nor whole/an integer)
it would be 0.2 + 2.5 = 2.7 btw
or
1/5 + 5/2
= 2/10 + 25/10
= 27/10
Answer:
3^6 i think
Step-by-step explanation:
Answer:
