Answer:
The solution is the point (0.5,-3)
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by substitution
Substitute equation B in equation A
Solve for x
Adds 5 both sides
Divide by 4 both sides
therefore
The solution is the point (0.5,-3)
<em>Verify your answer using the graph</em>
using a graphing tool
Remember that the solution of the system of equations is the intersection point both graphs
The intersection point is (0.5,-3)
therefore
The solution is the point (0.5,-3)
see the attached figure
Look at the picture.
The area of the hexagon is equal six times the area of the <span>equilateral triangle.
The formula of the </span><span>equilateral triangle with the leg a:
Therefore the formula of the area of the hexagon with a side lenght a is:
We have a = 12cm. Substitute:
