Brent has two barcode printing machines. each machine can print 25 barcodes per minute. on day 1, only the first machine was used, and it printed 95 barcodes. on the following day, the first machine printed for x minutes and the second machine printed for y minutes. which expression shows the total number of barcodes printed by both machines during these two days? (1 point)

95 + 25x + 25y

120x + 25y

25 + 95x + y

95x + 50y

The answer is A, 95 + 25x +25y

trust me, i took the test

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  

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
