Question

Brodrick correctly represents a composite number as the product of a pair of prime factors. Which equation could show Brodricks work? F-5×15=75 G-7×17=119 H-9×19=171 J-11×21=231

Answer 1

G-7×17=119

Explanation:

A prime number is a number which has only two factors, 1 and itself.

A composite number on the other hand is any number that has more than two factors.

In the options

In F-5×15=75, 15 can still be decomposed into 5X3

In H-9×19=171, 9 can still be decomposed into 3X3

In J-11×21=231, 21 can still be written as 7X3.

So option G is the only equation which could show Brodricks work.
