Find the difference.
MrMuchimi

To find the difference of the given expression, first step is to get rid of parenthesis. So, distribute negative sign to each terms of the second parenthesis. Hence,

(9x² + 10x + 4) - (9x² + 5x - 1)

= 9x² + 10x + 4 - 9x² - 5x + 1.

= (9x² - 9x²) +(10x - 5x) + (4 + 1) Group the like terms.

= 0 + 5x + 5 Combine the like terms.

= 5x + 5.

So, first choice is correct.

Hope this helps you!

Answer:

m=12f

Step-by-step explanation:

The measurement in inches =m

The measurement  in feet = f

We are told that: m varies directly with f

Written mathematically:

m\propto f

Introducing the constant of variation, we have:

m=k f

Given that: k=12

The equation relating these two quantities is:

m=12f
