Answer:
6.5
Step-by-step explanation:
43.50-24=19.5
19.5/3=6.5
X=13 is the awnser for this
Answer:
28s + 28
Step-by-step explanation:
simply multiply 7s and 7 by 4
A + b + c = 12
c = (a + b) - 2.....c - a - b = -2
3a + 1 = 2c
add the first 2 equations
a + b + c = 12
-a - b + c = -2
------------------add
2c = 10
c = 5 <== longest side is 5
sub in 5 for c in the 3rd equation
3a + 1 = 2c
3a + 1 = 2(5)
3a + 1 = 10
3a = 10 - 1
3a = 9
a = 3 <== shortest side
now sub in 5 for c and 3 for a back into the first equation
a + b + c = 12
3 + b + 5 = 12
b + 8 = 12
b = 12 - 8
b = 4 <== other side
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.
