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.
Hopes this loves.

meriva
The correct choice is A. When something is being increased by a percentage, you add the percentage to 100%, so you add 35% to 100% to make a decimal of 1.35.  Every year the initial value of 590 will be increased by 35%. so the correct choice is A.

Answer: total length of frame material is 3.2 meters

Step-by-step explanation:

The perimeter of an object or a plane shape is the distance around the object of plane shape.

Mila plans to frame a poster she bought at a concert. The total length of frame material that she needs would be the perimeter of the rectangular frame. The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(length + width)

The frame will be rectangular with a base of 0.65 meters and a height of 0.95 meters. Therefore,

Perimeter = 2(0.65 + 0.95)

= 3.2 meters
