A fence is to be built around an entire rectangular field which measures 210 ft by 173 ft. If fencing costs $4.29 per foot, what will the cost be of the fence? (Step by step response please)

The rectangle has two sides 210 ft and 2 sides 173 ft.

Find total feet of fence by adding all four sides:

Total fence needed : 210 + 210 + 173 + 173 = 766 feet.

Multiply total feet by cost per foot:

766 feet x 4.29 = 3,286.14

Cost: $3,286.14

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
