Why is this a square root answer? by the rule that if two chords intersect in a circle, then the product of the one chord's segments are congruent to the product of the other chords' segments, the answer is 64.

explain the process good for brainliest.

using the intersecting chord theorem:

qj x pq = lq x mq

using what you have :

qj x pq = 10 x 8

qj x pq = 80

you are told qj = 4 x pq:

(4 x pq) x pq = 80

simplify:

4pq^2 = 80

divide both sides by 4:

pq^2 = 20

take the square root of both sides:

pq = +/-sqrt(20)

pq = 2sqrt(5)

now you have qj = 4 x pq = 4 x 2sqrt(5) = 8 sqrt(5)

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
