Answer:

d = 36 km

Step-by-step explanation:

Speed of Jim, v = 18 km/h

Time, t = 2 hours

We need to find the distance covered. We know that the speed of an object is equal to the distance covered by it divided by total time taken.

$v=\dfrac{d}{t}\\\\d=v\times t\\\\d=18\ km/h\times 2\ h\\\\=36\ km$

So, he will cover 36 km.

Determine the prime factorization of 36. 62 22 · 9 22 · 32 4 · 9

larisa [96]

ANSWER
The prime factorization of 36 is
${2}^{2} \times {3}^{2}$

EXPLANATION

We want to find the prime factorization of 36.

The prime numbers that are factors of 36 are
$2 \: and \: 3$

So we find the number of times these two prime factors will multiply to get 36.

Thus,

$36 = 2 \times 2 \times 3 \times 3$

Thus gives
$36 = {2}^{2} \times {3}^{2}$
