Last year at a certain high school, there were 125 boys on the honor roll and 80 girls on the honor roll. This year, the number of boys on the honor roll decreased by 8% and the number of girls on the honor roll decreased by 5%. By what percentage did the total number of students on the honor roll decrease? Round your answer to the nearest tenth (if necessary).

Add 125 + 80

Step-by-step explanation:

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
