Answer:
HK = 20
Step-by-step explanation:
LM = (1/2) HK {Mid point theorem}
![10x - 90 = \frac{1}{2}(10x - 80) \\](https://tex.z-dn.net/?f=10x%20-%2090%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2810x%20-%2080%29%20%5C%5C)
2*(10x - 90) = 10x - 80
2*10x - 2*90 = 10x - 80
20x - 180 = 10x - 80 {add 180 to both sides}
20x = 10x - 80 + 180
20x = 10x +100 {Subtract 10x from both sides from }
20x -10x = 100
10x = 100
x = 100/10
x = 10
HK = 10x - 80
= 10*10 - 80
= 100 - 80
= 20
Answer:
-13 + 5*n-1 I think
Step-by-step explanation:
Answer:
46656
Step-by-step explanation:
6x6x6x6x6x6x6 can be written in its index form as 6⁷
6x = 6⁷
6x = 279936
Applying change of subject formula, divide both sides of the equation by 6
6x/6 = 279936/6
x = 46656
