Step-by-step explanation:
![\frac{ - 3 + 4 }{2} = \frac{1}{2} \\ \frac{ - 4 + - 1}{2} = \frac{ - 5}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%203%20%2B%204%20%7D%7B2%7D%20%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%20%5C%5C%20%20%20%5Cfrac%7B%20-%204%20%2B%20%20-%201%7D%7B2%7D%20%20%3D%20%20%20%5Cfrac%7B%20-%205%7D%7B2%7D%20%20)
Answer:2.31
Step-by-step explanation: considering that the root of 3 has already been given. Will just divide 4 by the root of 3 which is 1.73. and the answer it gives is 2.31
23
Step-by-step explanation:
![f(3) = {(3)}^{2} + 3(3) - 7 = 9 + 9 - 7 \\ = 18 - 7 = 11](https://tex.z-dn.net/?f=f%283%29%20%3D%20%20%7B%283%29%7D%5E%7B2%7D%20%20%2B%203%283%29%20-%207%20%3D%209%20%2B%209%20-%207%20%5C%5C%20%20%3D%2018%20-%20%207%20%3D%2011)

Answer:
HJ = 8 JE = 4
Step-by-step explanation:
it is given that H is the midpoint of GE and J is the midpoint of FE. According to the midpoint theorem the line segment connecting the midpoint of two sides is parallel to the three side and its length is half of the third side. since JH is connecting the midpoints.
HJ= 1/2 (GF)
x + 3 = 1/2 (4x - 4)
x + 3 = 2x - 2
x = 5
^ Thus meaning the value of x is 5.
Now you just fill into your equations:
HJ = x + 3 = (5) + 3 = 8
JE = x - 1 = (5) - 1 = 4
Therefore, HJ = 8; JE = 4.
