Remember you can do anything to an equaiton as long as you do it to both sides
3-2(2x-3)=17
minus 3 from both sides
3-3-2(2x-3)=17-3
-2(2x-3)=14
divide both sides by -2
2x-3=-7
add 3 to both sides
2x+3-3=3-7
2x=-4
divide both sides by 2
x=-2
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)
