Answer:

Option B, 3^2 * 5

Step-by-step explanation:

<u>Step 1:  Find the prime factorization of 45</u>

45 = 9 * 5

9 can be simplified as 3^2

5 cannot be simplified because it is a prime number

9 * 5

3^2 * 5

<em>So, 45 = 3^2 * 5</em>

Answer:

3^2X5

Step-by-step explanation:

Students learn that the prime factorization of a number is the given number written as the product of its prime factors. For example, to find the prime factorization of 45, use a factor tree to find that 45 is 5 x 9, and 9 is 3 x 3. So the prime factorization of 45 is 5 x 3 x 3, or 5 x 3^2.

Solve the Equations
kkurt [141]

Answer and Step-by-step explanation:

1) - 6.5 r = - 58.5

- r = - 58.5/6.5

- r = - 9

<h2>r = 9 </h2>

2) c - 5.5 = 2.3

c = 2.3 + 5.5

<h2>c = 7.8</h2>

3) 56 = - 5.6s

56/5.6 = - s

10 = - s

- 10 = s

<h2>s = - 10</h2>

4) d/4 = 4.7

d = 4.7 / 1/4

d = 4.7 * 4

<h2>d = 18.8</h2>

5) - 9 = 6.9 + x

- 9 - 6.9 = x

- 15.9 = x

<h2>x = - 15.9</h2>

6) 23.5 = 4.7z

23.5/4.7 = z

5 = z

<h2>z = 5</h2>

7) - 2.7 = v + 4.9

- 2.7 - 4.9 = v

- 7.6 = v

<h2>v = - 7.6</h2>

8) 2.6 = k/3

k/3 = 2.6

k = 2.6 / 1/3

k = 2.6 * 3

<h2>k = 7.8</h2>

9) - 5.6f = 44.8

- f = 44.8/5.6

- f = 8

<h2>f = - 8</h2><h2 />

hope it helps, my friend
