Answer:
x=-11
Step-by-step explanation:
-9x-4-8+7x=10
-2x-12=10
+12 +12
-2x=22
-2x/-2=22/-2
x=-11
26+35+10+18+15+37+25+20+15/9= 22.33
You can see if there are any patterns and then subtract the first number to the next , finding the X & Y
Answer:
=4sqrt(10)
Step-by-step explanation:
The geometric mean of two numbers is sqrt(a*b) where a and b are the two numbers
geometric mean = sqrt(8*20)
=sqrt(160)
= sqrt(16*10)
We know that sqrt(ab) = sqrt(a) sqrt(b)
=sqrt(16) sqrt(10)
=4sqrt(10)
