Answer:
hm im not so sure
Step-by-step explanation:
Gcf will be the product of 2 and 8
Answer:
a = 12 and b = 18
Step-by-step explanation:
Given that,
8,a,b,27 are in geometric sequence.
For a GP, the nth term is given by :
Put n = 4
Put n = 2,
Put n = 3
So, the values of a and b is 12 and 18 respectively.
Answer:
√10
Step-by-step explanation:
Pythagorean theorem. a^2+b^2=c^2.
In this case 9^2+b^2=√91^2. That equals 81+b^2=91. You isolate b^2, b^2=10. So b=√10.
