Britney scored an 85 on her last math test write the prime factorization on 85 ​
7nadin3 [17]

Answer:

5 \times 17

Step-by-step explanation:

Just so you know, for your information, composite numbers have more than <em>two</em> factors, and prime numbers have EXACTLY two factors [1 and itself (that number)].

* A common mistake is that people make is that they say that all even numbers are composite, and that is false because there are odd numbers that are PERFECT SQUARES and can be divided evenly without leaving a remainder. So, using the Prime Factorization Method, you can do this in two structures:

  • Ladder Diagram
  • Factor Tree

Factor Tree

85

/ \

17 5

Ladder Diagram

17|<u>85</u>

5|<u>5</u>

1

In the Ladder Diagram, when you are down to 1, you know that factorization is over and there is nothing else to do.

So, with that being said, the prime factorization of 85 is 17 × 5.

I am joyous to assist you anytime.

Evaluate bd for a = 5, b = -2, c = 4 and d = -6. user: perform the indicated operation. (-50) �� (-2) user: perform the indicate
Stella [2.4K]
Assuming that the missing operations are multiplication as it is with the first question "bd", then the answer would be as follows:

1.)  Simply substitute the values of b and d before multiplying.

bd = (-2)(-6) = 12

2.) (-50)(-2) = 100

3.) (5/8)(7/12)= 35/96
