-12=2k means k is -6
-w^2 =-81 so w =9
2f=-14 so f=-7
Answer:
no solution
Step-by-step explanation:
if you do 3*6= 18 and 3+14 is 17 so 18=17 is not true therefore it has no solution
Since rectangle can be a square, and square has the greatest area among quaderlaterals with equal perimeter, the sides would be 10, making the are 100.
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.
