write the following statements as mathematical implications:

(c) "it is necessary that positive numbers are > 7.

(d) to show a number is +, it is sufficient to show it is > 10.

Lets say that

p: x is a positive numbre

q: x > 7

r : x > 10

Then,

(C) if 'p', then 'q' (if a number is positive, then it is >7)

p》q

(D) if 'r', then 'p' (if a number is >10 then it is positive)

r》p

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.

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?
