Answer:
x = 5
Step-by-step explanation:
A by B is simply 
3 by x + 1 is 
5 by 2x is 
So, the equality is ;
=
Cross multiply and solve the inequality;
3(2x) = 5(x + 1)
6x = 5x + 5
6x -5x = 5
x = 5
Answer:
Step-by-step explanation:
x² + 9x+8 = (x+1)(x+8)
Remark
You'll see it a whole lot easier if you make a substitution so that it looks like something you have already seen
Solution
let y = x^2
x^4 = x^2 * x^2
x^4 = y * y
x^4 = y^2
Now the expression becomes
y^2 + 8 y - 9 = z
(y + 9)(y - 1) = z
Now put the x^2 back in.
(x^2 + 9) ( x^2 - 1) = z
x^2 - 1 becomes x + 1 and x - 1. At this level x^2 + 9 can't be factored.
Answer
(x^2 + 9) (x + 1)(x - 1)
