Evaluate 1+(-2/3)-(-m)where m = 9/2

answer:

  29/6

Step-by-step explanation:

Putting the value where the variable is and eliminating excess signs, we have ...

  1 - 2/3 + 9/2

  = 6/6 -4/6 + 27/6

  = 29/6 = 4 5/6

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

i dont know if you cant find a way its best to actually add all of them start from 105 tho
