Answer:
D. The inequality has an equal sign it
Step-by-step explanation:
We use solid lines whenever the inequality contains or . That means it contains an equal sign which means the boundary line is inclusive.
On the other hand when the inequality does not have an equal sign in it we use a dashed line to indicate that all values on the boundary line are not inclusive.
That is we use a dashed or broken line for the boundary line of an inequality whenever it contains .
The correct answer is D

Answer:
(90,60)
Step-by-step explanation:
Answer:
55 meters squared
Step-by-step explanation:
SA = sum of all the areas of the sides
The pyramid has four faces, which we have to add together:
SA = 3(long face area) + base area
Area of a triangle = 1/2 base * height
Area of the base = 1/2 * 3.5 * 4 = 7 meters squared
Area of a long face = 1/2 * 8 * 4 = 16 meters squared
Coming back to our surface area formula, we can plug those areas in:
SA = 3(long face area) + base area
= 3(16) + 7 = <u>55 meters squared</u>
