Answer:
C
Step-by-step explanation:
Inequalities of the type | x | > a, always have solutions of the form
x < - a or x > a, that is
Given
| 2x + 10 | > 26, then
2x + 10 < - 26 OR 2x + 10 > 26 ( subtract 10 from both sides of both )
2x < - 36 OR 2x > 16 ( divide both sides by 2 of both )
x < - 18 OR x > 8 → C
Area of the figure=area of the square - area of the rectangle 1 - area of the rectangle 2.
Area of the square=side x side=12 * 12 =144
Area of the rectangle 1=8 *5=40
Area of the rectangle 2=5 * (12-8)= 5 * 4=20
Area of the figure=144 - 40 -20=84
Answer : 84
