Area of deck= 2(20w)+4(w^2)+2(50w)d
456=2(20w)+4(w^2)+2(50w)

456=40w+4w^2+100w

456=4w^2+140w

114=w^2+35w

0=w^2+35w-114

find what 2 numbers multiply to get 114 and add to get 35 and factor

-3 and 38

0=(w-3)(w+38)

set each to zero

w-3=0

w=3

100 Points and Brainliest.
hichkok12 [17]

Answer:

See below ↓

Step-by-step explanation:

We have a graph given to us.

⇒ Take the points to form an equation!

<u>The points</u>

  • (4, 6)
  • (-2, 1)

<u>Making an equation</u>

  • Find the slope
  • m = 1 - 6 / -2 - 4
  • m = -5 / -6
  • m = 5/6

  • Take one of the two points and substitute in the equation :
  • ⇒ y - y₁ = m (x - x₁)
  • ⇒ y - 6 = 5/6 (x - 4)
  • ⇒ y - 6 = 5x/6 - 10/3
  • ⇒ <u>y = 5x/6 + 8/3</u>
  • ⇒ or <u>6y = 5x + 16</u>
