The greatest common factor is
EXPLANATION
We want to find the greatest common factor of
and
The prime factorizations are;
and
The product of the least powers of the common factors is the greatest common factor.
First term: -9
Common difference: 7
a(n) = -9 + 7(n-1), for n = {1, 2, 3, ... }
Check: what is the first term? let n=1. Then a(1) = -9 + 7(1-1) = -9.

<u>Answer:</u>
5.65 cm
<u>Step-by-step explanation:</u>
We are given that the length of each leg of an isosceles right triangle is 4 cm and we are to find the length of the hypotenuse.
For this, we will use the Pythagoras Theorem:
where 
is the hypotenuse.
Therefore, the length of the hypotenuse is 5.65 cm.
