Simplify the following surds:
a. √50=
b. √5+√8-√20+√2=
c. -6√20+2√45+7√5=

a= 7.07

b= 2.006

c= -2661.542

Step-by-step explanation:

Calculate all of the square roots and follow through :))

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
