Find the length of the third side. If necessary, write in simplest radical form.
3
6

5.2 units

Step-by-step explanation:

This is a right-angled triangle which means that the missing length can be solved using the Pythagorean theorem:

c² = a² + b²

Where c is the hypotenuse

a and b are the other sides.

c =  6

a = 3

b = ?

6² = 3² + b²

36 = 9 + b²

b² = 27

b = √27

b = 5.2 units

what the question so we can you out

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
