Which ratio compares the number of students in the Spanish club to the total number of students?
19:95
20:95
95:24
95:19

A, 19:95

Step-by-step explanation:

there are 19 Spanish students and 95 total students

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  

based on context clues you gave i'm assuming the answer would be c.
