Answer:
Because a bracket is used, the solution includes 
The solution includes numbers from negative infinity to 
Step-by-step explanation:
we know that
If the solution for an inequality is (–∞, 6.5]
then

The solution is all real numbers less than or equal to 
so
Because a bracket is used, the solution includes 
The solution includes numbers from negative infinity to 
Answer:
a = 64
Step-by-step explanation:
The geometric mean of 2 numbers a and b is
, then
= 16
( square both sides )
28a = (16
)² = 1792 ( divide both sides by 28 )
a = 64
Answer:
12 R 147
Step-by-step explanation:
a+b+c=9 and a2+b2+c2=35 then by using identity
(a+b+c)2=a2+b2+c2+2ab+2bc+2ca,we get the answer 9x9=35+2(ab+bc+ca)
2(ab+bc+ca)=9x9-35
2(ab+bc+ca) =81-35then we get ab+bc+ca=46/2 so ab+bc+ca=23
