<h3>Explanation:</h3>

2 1/2 is the sum (2 + 1/2). The distributive propertly lets you multiply 12 by each of the terms of this sum and add the products.

12 × (2 1/2) = 12×2 + 12×(1/2) = 24 + 6 = 30

What is the product of 2x - 5 and 3x2 + 5x - 7? Write your answer in standard form.
andrew11 [14]

Answer:

a) 6x³ − 5x² − 39x + 35

b) no

Step-by-step explanation:

(2x − 5) (3x² + 5x − 7)

Distribute:

3x² (2x − 5) + 5x (2x − 5) − 7 (2x − 5)

Distribute again:

6x³ − 15x² + 10x² − 25x − 14x + 35

Combine like terms:

6x³ − 5x² − 39x + 35

5x − 2 is the opposite of 2x − 5, so you would get the negative of the answer from part (a).

There are 15 technicians and 11 chemists working in a research lab. They need to form a 5 person safety committee. In how many w
Burka [1]
<h2>There are a total 65,780 ways in which the committee can be made of 5 members.</h2>

Step-by-step explanation:

Here, the total number of technicians in the lab = 15

The total number of chemists in the lab  = 11

So, the total members in the lab  = 15 + 11 = 26

So, there are total 26 eligible candidates in the lab from which committee of 5 people has to be made.

Now, since there is <u>no restrictions</u> on the choice, so the committee can be formed in nay way, such that:

It may or may not have any technician.

It may or may not have may chemists.

So, the number of ways 5 member can randomly be chosen from a committee of 26 people  = ^{26} C_5

^{26} C_5 = ^{26} C_5 = \frac{26!}{5! \times 21!}  = 65,780

Hence, there are a total 65,780 ways in which the committee can be made of 5 members.
