1. let x is the width

then

length = 2x

premiter = 2*( 2x+x) =  96

2. 3x = 24

3. let number is x

2/3 * x = 72

4. let two numbers are x, x+1

x + x +1 = 29

5.let number is x

then

4x+8 = 54

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
