Let the function equal 416 and solve for x.

2x^2 - 6x = 416

2x^2 - 6x - 416 = 0

x^2 - 3x - 208 = 0

(x - 16)(x + 13) = 0

x - 16 = 0   or   x + 13 = 0

x = 16   or   x = -13

Since the number of rows cannot be negative, discard the -13 solution.

Answer: There are 16 rows.

The answer is D.
f(x) = 2x^2-6x
416=2x^2-6x
208=x^2-3x
0=x^2-3x-208
0=(x-16)(x+13)
x=16 x can not be equal to -13.

Answer:

Perimeter = 21.58 units

Step-by-step explanation:

Perimeter of a polygon = Sum of measures of all sides of the polygon

Perimeter of the quadrilateral LEAP = PL + AE + EL + LP

                                                            = 4.47 + 4.47 + 6.32 + 6.32

                                                            = 21.58 units

[If the distances between two point are not given, use the formula to calculate the distance between two points (x_1, y_1) and (x_2,y_2)

Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}]

aliya0001 [1]

Answer:

Are they going to build the fence on the edge of the pool?  How are they going to get into the pool?  This question is illogical, however....

Step-by-step explanation:

A square pool is also wierd.

Volume Pool = side × side × depth

Volume Pool / depth = side²                 solve for side

side² = Volume Pool / depth

the fence is 3.5 feet tall

Fencing sqft one side = side × fence height  for ONE side

Total Fencing = 4 × Fencing sqft one side

side² = 3464 ft³ / 8 ft

         = 422 ft²

side  =  √422 ft²

        =  20.54 ft

Fencing area one side  = 20.54 × 3.5

       = 71.899 ft²

Total fencing = 4× 71.899 ft²

      = 287.6 ft²      to the nearest tenth     <--------------------   FINAL ANSWER
