Hi there
Root=0.5 means x=0.5
Plug in 0.5 for x
(b-5)0.5^2-(b-2)0.5+b=0
(b-5)0.25-(b-2)035+b=0
Simplify
0.75b-2.25=0
b=3
Hope this helps
They got the 1.2 minutes by taking the total number of minutes (6) and dividing them by the number of laps run (5). So 6 divided by 5 gives you the 1.2.
There are many. For example, 32 x 0.5 is 16. You can multiply 4 x 4 to get 16, so it is rational.
Answer:
a=48 units^2
Step-by-step explanation:
The area of a rectangle can be found using:
a=bh
We know the base is 6, and the height is 8, so we can substitute them in
a=6*8
a=48
Area uses units squared, so,
a=48 units^2
