Answer:
D
Step-by-step explanation:
20x + 12 x =14x +30
20x - 14x = 30-12
6x= 18
6x/6 = 18/6
x = 3
so xs =3
Answer:
1400 square units
Step-by-step explanation:
The area can be computed by subtracting the areas of the white rectangles at three corners from the overall 60×30 rectangle.
The upper left corner white space is 10×10 = 100 square units.
The upper right and lower left white spaces are 15×10 = 150 square units each.
Then the shaded area is ...
60×30 -100 -2(150) = 1800 -100 -300 = 1400 . . . square units
_____
<em>Alternate solution</em>
You can extend each of the horizontal edges across the figure to divide it into three rectangles. From the top down, these have dimensions and areas of ...
35×10 +60×10 +45×10 = 10(35+60+45) = 10(140) = 1400 . . . square units
__
