Step-by-step explanation:

just add the two functions

5x^2 - 8x^2 = -3x^2 etc

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.

people grow faster than other people.

step-by-step explanation:

should you really be posting this isn't math boi.
