2 times x -4=12
2x-4=12
Let x= 8
(2.8)-4=12
16-4= 12
So the answer is 8
Answer:
41/12
Step-by-step explanation:
3 x 12 = 36 then you add 5 to get 41.
We need to expand the square binomial and then multiply:
<span>3x(x + 3)^2
= 3x(x + 3)</span>(x + 3<span>)
= 3x(x^2 + 6x + 9)
= 3x^3 + 18x^2 + 27x</span>

This can be considered as a very easy Question where you have to find the value of √85 and √86 upto 2 decimal places then we could find it easily.
Let's start!
Value of √85=9.21
Value of √86=9.27
Now it is obvious that 9.25 lies between √85 and √86.
