I'm pretty sure the answer is B if you're using basic math [15+15+9+4=43]
78-43=35. Hope this helps.
The set X is convex.
In geometry, a subset of an affine space over the real numbers, or more broadly a subset of a Euclidean space, is said to be convex if it contains the entire line segment connecting any two points in the subset. A solid cube is an example of a convex set, whereas anything hollow or with an indent, such as a crescent shape, is not. Alternatively, a convex region is a subset that crosses every line into a single line segment.
b)The set X is convex as any two points on the set X is included in the whole set as x>0. So a line joining any two points on the set X is completely inside the set x.
c)set X is not a closed set as the compliment of the set is not an open set.
d)Set X is not bounded. If a set S contains both upper and lower bounds, it is said to be bounded. A set of real numbers is therefore said to be bounded if it fits inside a defined range. hence set x is not bounded.

Answer: x = 18
Step-by-step explanation:
The percent change is 75%
Here's the math:
First, we need to find out how many more 63 is than 36. We can do that by subtracting.
63 - 36 = 27
We could write an expression like this: 36 + 27 = 63.
The reason we wrote it like that was because we started off with 36, so writing it like that, we already know that the percent change will be less than 100% since 36 is 100%.
Now we need to find what percent of 36, 27 is since we started off with 3. To do that we divide 36 ÷ 27 and we get .75. Now that we have a decimal, to change it to a percent, we just multiply my 100 and we get 75. So 27 is 75% of 36.
Since it is 75% of 36 and is added to 36 to get 63, 75% is our percent change!
Thank you for your question! I hope this helped! Have an amazing day! :D
First spilt the shape into two smaller shapes to get a rectangle and a parallelogram use the area of a rectangle formula to get an area of 15 units for the rectangle and the use the parallelogram formula to get 15 units the. Add the area of both shapes to get 30 units
