You have to add the areas of the three rectangles.
A1 = 39*11 = 429 m²
A2 = (39-12)*7 = 27*7 = 189 m²
A3 = 10*6 = 60 m²
A = 429 + 189 + 60 = 678 m².
Hope this helps !

Answer:
D. x2 + x - 20.
Step-by-step explanation:
(x – 4)(x + 5).
= x(x + 5) -4(x + 5).
= x2 + 5x – 4x – 20.
= x2 + x - 20.
-1.6 , -6/5 , -0.875, 0.9, 2.5
The negative number many seem high but since the greatest negative number is closer to zero it is higher than the other negative numbers.
