Answer:

I gotchu, it's A. x > -2

Step-by-step explanation:

The circle on the line is open so it means less than or greater than. If it was a close circle, it would be less than or equal to and vice versa. And the number is -2. The line excludes -2 but includes all numbers greater than that. So the answer would be A. x > -2

Allushta [10]
  • Answer:

<em>l = 16 feet</em>

<em>w = 3 feet</em>

  • Step-by-step explanation:

<em>A = l×w</em>

<em>l = 10+2w</em>

<em>48 = (10 + 2w)w</em>

<em>48 = 10w + 2w² | : 2</em>

<em>24 = 5w + w²</em>

<em>w² + 5w - 24 = 0</em>

<em>w² + 8w - 3w - 24 = 0</em>

<em>w(w + 8) - 3(w + 8) = 0</em>

<em>(w - 3)(w + 8) = 0</em>

<em>w - 3 = 0 => w = 3 feet</em>

<em>w + 8 = 0 => w = - 8 ∉ N </em>

<em>l = 10 + 2w</em>

<em>l = 10 + 6</em>

<em>l = 16 feet</em>

<em />

<em>A = l×w = 16ft×3ft = 48ft² </em>
