Step-by-step explanation:
triangle formula is ½*b*h
so 5*8 is 40
1/2 of 40 is 20cm
1/2means divideby2soitis40/2
Answer:
20
Step-by-step explanation:
5 times 8 divided by 2 is 20, and you have to make sure to divide bc its a triangle
+8=54
x+2/2x−2 = 1/2
Answer:
no solutions
Step-by-step explanation:
x+2 1
------------- = ----------
2x-2 2
We can solve this using cross products
(x+2) *2 = 1*(2x-2)
Distribute
2x+4 = 2x-2
Subtract 2x from each side
2x-2x+4 = 2x-2x-2
4 = -2
This is never true so there are no solutions
Answer:
Step-by-step explanation:
First cross multiply:
2(x+2)=2x-2
Then Simplify:
2x+4=2x-2
Finally, Solve:
2x-2x=4+2
