Answer:
0 is real number, rational number, integers, whole numbers,
Answer:
B : The width of the interval would increase
Step-by-step explanation:
We have formual for area of rectangle A=l*w where l is length and w is width. We can transform it to obtain width
A=l*w /:l (divide both sides by l)
Knowing that A=189 and l=21 we can substitute our data to the formula
w=
- its the result
1. N is a midpoint of the segment KL, then N has coordinates
2. To find the area of △KNM, the length of the base MK is 2b, and the length of the height is a. So an expression for the area of △KNM is
3. To find the area of △MNL, the length of the base ML is 2a and the length of the height is b. So an expression for the area of △MNL is
4. Comparing the expressions for the areas you have that the area is equal to the area . This means that the segment from the midpoint of the hypotenuse of a right triangle to the opposite vertex forms two triangles with equal areas.
