Find the additive inverse of 9/10 need help

The Additive inverse only works when you add a to its oppositie leaving a sum of 0

For example, says 5 represents a.

5 + b = 0

B, is 5's additive inverse: -5

The reciprocal of 9/10, however, is 10/9

The additive inverse of -9/10 is 9/10.

Step-by-step explanation:

answear:

a

step-by-step explanation: a

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.
