Answer:
A. d ≤ –7 or d > 8.
Step-by-step explanation:
Given : 2d + 3 ≤ –11 or 3d – 9 > 15.
To find : What are the solutions of the compound inequality .
Solution : We have given 2d + 3 ≤ –11 or 3d – 9 > 15.
For 2d + 3 ≤ –11
On subtracting both sides by 3
2d ≤ –11 - 3 .
2d ≤ –14.
On dividing both sides by 2 .
d ≤ –7.
For 3d – 9 > 15.
On adding both sides by 9.
3d > 15 + 9 .
3d > 24 .
On dividing both sides by 3 .
d > 8 .
So, A. d ≤ –7 or d > 8.
Therefore, A. d ≤ –7 or d > 8.
Answer: inconsistent
Step-by-step explanation:
Inconsistent systems have two lines that are two independent equations that don’t overlap. Basically, if the lines are parallel, the system will always be inconsistent.
The equation would be 60h=m

The area of the composite figure with 3 semicircles connected to 3 sides of a square is (6π+16)
.
<h3 /><h3>What is a semicircle?</h3>
A semicircle is a plane shape that is a part of a circle divided into two equal parts through its diameter.
Analysis:
Since the semicircles are connected to 3 sides of a square 4cm, the diameter of the semicircle is 4cm.
Radius of semicircle = 4/2 = 2cm
Area of a semicircle = π
/2 = 
/2 = 2π
For three semicircles = 3 x 2π
= 6π
Area of square =
=
= 16
Area of composite figure = Area of 3 semicircles + area of square
Area of composite figure = (16 + 6π)
In conclusion, the area of the composite figure is (16 + 6π)
.
