Answer:
I think that the answer is 'sale'.
Step-by-step explanation:
The shape of the cross-section is a rectangle Then the area of the rectangle ACHE will be 22.63 square units.
<h3>What is Geometry?</h3>
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
A cube with a side length of 4 units is given.
Then the shape of the cross-section formed when a plane containing line AC and line EH intersects this cube will be a rectangle.
Then the area of the rectangle ACHE will be
The length of AC or HE will be 4√2.
Then we have
Area = 4 x 4√2
Area = 22.63 square units
The shape is determined because the section is a surface and the dimension of the surface are different.

The given sequence shows an Arithmetic sequence; such that
![First\ Term = T_1 = 125](https://tex.z-dn.net/?f=First%5C%20Term%20%3D%20T_1%20%3D%20125)
![Common\ Difference = d = 143 - 125](https://tex.z-dn.net/?f=Common%5C%20Difference%20%3D%20d%20%3D%20143%20-%20125)
![d = 18](https://tex.z-dn.net/?f=d%20%3D%2018)
The general formula (Tn) is as follows:
![T_n = T_1 +(n - 1)d](https://tex.z-dn.net/?f=T_n%20%3D%20T_1%20%2B%28n%20-%201%29d)
Substitute values for T1 and d
![T_n = 125 +(n - 1) * 18](https://tex.z-dn.net/?f=T_n%20%3D%20125%20%2B%28n%20-%201%29%20%2A%2018)
Open Bracket
![T_n = 125 +18n - 18](https://tex.z-dn.net/?f=T_n%20%3D%20125%20%2B18n%20-%2018)
Collect Like Terms
![T_n = 125 - 18+18n](https://tex.z-dn.net/?f=T_n%20%3D%20125%20%20-%2018%2B18n)
![T_n = 107+18n](https://tex.z-dn.net/?f=T_n%20%3D%20107%2B18n)
