When both parties discuss the terms of a contract they are
marysya [2.9K]
B - Negotiating.

This is because they are communicating, they haven't yet agreed to anything or committed to the contract as neither parties have signed, thus leading to both C and D to be incorrect.

A, however, is not exactly a term used for this situation - contracting is more of a term used to say someone contracted a disease or the flu or etc. 

Therefore, B would be correct as they are indeed negotiating the terms of the contract.

Hope this helps!

Dominik [7]
The combination formula is given by

C(n, r) = \frac{n!}{(n-r)!r!}

C(11, 8) = \frac{11!}{(11-8)!8!}

C(11, 8) = 165

So, there are 165 ways of choosing 8 flowers out of 11 flowers

The area of a circle is 28.26 square kilometers. What is the circles diameter
irinina [24]

Answer:

6km

Step-by-step explanation:

Area of circle = πr²

Where r = radius,  π= 3.14, A = 28.26km²

A = 3.14 x r²

3.14 r2 = 28.26

Divide both sides by 3.14

r²= 28.26/3.14

r² = 9

Square root both sides

r= √9

r= 3

Radius = 3km

Note : Diameter = 2 x radius

Diameter = 3 x 2

Diameter = 6km

I hope this was helpful, Please mark as brainliest.

What is the determinant ? <br>ANS : -2 <br>plz help me with process​
WITCHER [35]

Answer:

(-2)

Step-by-step explanation:

We have to find the determinant of the given matrix,

A=\begin{bmatrix}(a-1) & (a^2-a+1)\\ (a+1) & (a^2+a+1)\end{bmatrix}

det A = (a - 1)(a² + a + 1) - (a + 1)(a² - a + 1)

         = a(a² + a + 1) - 1(a²+ a + 1) - a(a² - a + 1) - 1(a² - a + 1)

         = a³ + a² + a - a² - a - 1 - a³ + a² - a - a² + a - 1

         = (a³ - a³) + (-a² + a² - a² - a²) - 1 - 1

         = -2

Therefore, determinant of the given matrix is (-2).
