Vertex = (-5,-4), y-intercept = (0,21), x-intercepts = (-7,0) and (-3,0), axis of

symmetry is x = -5

Answer:

204

Step-by-step explanation:

Find the area of the inner square. 14 x 14 = 196

Then find the area of the outer square. 20 x 20 = 400

Subtract 400 - 196 = 204

204 is closest to 200

Answer:

$( - 12 \div 3) \times ( - 8 + ({ - 4})^{2} - 6) + 2$

$= ( - 4) \times ( - 8 + 16 - 6) + 2$

$= ( - 4) \times (2) + 2$

$= - 8 + 2$

$= - 6$
