To find a shoe size, the manufacturer uses the equation S=3f-22
,
where S represents the shoe size and f represents the heel-to-toe length of the foot, in inches. Which of the following is the same equation solved for f in terms of S?

f=3 /S+22

f=S22/3
f=S/3+22
f=S+22 /3

D. f=S+22 /3

Step-by-step explanation:

S= 3fs-22

3f/3=S+22/3

f= S+22/3

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
