B

Step-by-step explanation:

For every performance, Jim's band charges;

$35+$20x (where x is the no. of hours spent in performing) as $35 is a constant charge

In his last performance, Jim's band charged $120 which is equal to $35 +$20x

=> $120 =$35+$20x

=> $20x = $120-$35= $85

=> x = 85/20 = 4¼/ hours = 4hrs 15 mins

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

x = -2

y = 848
