Answer:
=√85 is the simplified radical
As the GCF is 3x let us write a polynomial and then multiply it by 3x.
Here is a polynomial:

If we multiply it by 3x we get

. Since we have a product (two expressions being multiplied together) this is factored. So this is the factored form of the polynomial we created with GCF of 3x.
Let’s multiply the terms in the parenthesis by 3x to get the same polynomial but written a different way:

. This is the factorable polynomial and the one we had before is the factored polynomial (also an equivalent form)
To get another equivalent form I could multiply out only the first term. This gives us

another equivalent form.
Since $50 is the fixed rate that would be your y intercept. Since $25 is charged per hour, this value changes and is the slope. Therefore y=25x+50
Answer:

Step-by-step explanation:
Let the total amount be x
Then Ali got 1/8x With 7/8x left
Juma got 7/40x with 7/10x left
Musa, Khalid and Mustafa got 7/30x each
since 
7x=18000
