(z-8) (z+2) 
What I do to factor is find _x_=-16 and _+_=-6. -8x2=-16 and -8+2=-16. The coordinates for z if you were to graph this would be (8,0) and (-2,0)

A rectangle shed is fenced with 120ft long barbed wire. If length of the shed is twice as long as the width, that is the length?
creativ13 [48]

Answer:

40 ft  

Step-by-step explanation:

<em>Data: </em>

(1) P = 120 ft

(2) l = 2w

<em>Calculations: </em>

(3)  P = 2l + 2w           Substitute (1) and (2) into (3)

  120 = 2(2w) + 2w     Multiply

  120 = 4w +2w           Combine like terms

  120 = 6w                   Divide by 6

(4) w = 20 ft                Substitute (4) into (2)

      l = 2 × 20

      l = 40 ft

<em>Check: </em>

120 = 2×40 + 2×20

120 = 80 + 40

120 = 120
