a construction company charges $15 per hour for debris removal , plus a one -time fee for the use of the trash dumpster.the tota

ser-zykov [4K]

Let h be the numbers of hours, f be the one-time fee and c the cost charged. The equation is

$c=15h+f$

Since you pay $15 per four, plus the fee. We can solve this equation for the fee:

$f=c-15h$

If we plug c=195 and h=9, we have

$f=195-15\cdot 9=195-135=60$

(3x – 1)(2x +9)<br> Multiplying polynomials

ad-work [718]

We can use the FOIL method to simplify.

= (3x – 1)(2x + 9)

= (3x * 2x) + (3x * 9) + (-1 * 2x) + (-1 * 9)

= 6x + 27x + (-2x) + (-9)

= 33x - 11
