Answer:
7/20
Step-by-step explanation:
Convert them so they have the same denominator.
1/4 + 1/10
A common denominator is 40 (I'm just choosing an easy one for now, rather than the smallest one)
1/4 * 10/10 = 10/40
1/10 * 4/4 = 4/40
10/40 + 4/40
Add the numerators
(10 +4)/40 = 14/40
Simplify the fraction
14/2 = 7 40/2 = 20
7/20
The Pythagorean theorem tells you ...
... c² = a² + b²
... 13² = 12² + b² . . . . . fill in the given numbers
... 169 - 144 = b² . . . . .subtract 12²
... √25 = b . . . . . . . . . take the square root
... b = 5 . . . . . . The value of b you're looking for.

The numbers {5, 12, 13} make what is called a "Pythagorean triple" a set of integers that satisfies the relation of the Pythagorean theorem. These, and the triple {3, 4, 5} are often seen in algebra problems. It can be worthwhile to remember these numbers.
