x is greater than or equal to 6 so 5 and below are not a solution to this inequality.
8x+2 it’s correct because it’s correct
Answer:
The surface area is equal to 
Step-by-step explanation:
The surface area of the triangular pyramid is equal to the area of its four triangular faces
so
In this problem
![SA=4[\frac{1}{2}(b)(h)]](https://tex.z-dn.net/?f=SA%3D4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28h%29%5D)
we have


substitute the values
![SA=4[\frac{1}{2}(15)(13)]=390\ in^{2}](https://tex.z-dn.net/?f=SA%3D4%5B%5Cfrac%7B1%7D%7B2%7D%2815%29%2813%29%5D%3D390%5C%20in%5E%7B2%7D)
Hi there
-5i + 5-1 + 6
= -5i + 11- 1
= 5i + 10
That's the answer :0
I hope that's help... Do you have any question ?
Consider that the initial length and width of the rectangle are given as,

After the length is increased by 10%, the new length (L) of the rectangle is calculated as,

After the width is decreased by 10%, the new width (B) of the rectangle is calculated as,

Then the area (A) of the new rectangle is calculated as,

Thus, the new area of the rectangle is 396 square meters.
