Answer:

3 ways.

Step-by-step explanation:

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

2 meats from a set of 3(steak, fish or chicken). So

$C_{3,2} = \frac{3!}{2!1!} = 3$

3 ways.

Alborosie

Step-by-step explanation:

${9}^{ \frac{ - 1}{2} } \\ {3}^{2 \times - \frac{1}{2} } \\ {3}^{ - 1} \\ \frac{1}{3}$

Now for another

${27}^{ \frac{ - 2}{3} } \\ {3}^{3 \times \frac{ - 2}{3} } \\ {3}^{ - 2} \\ \frac{1}{9}$

<h2>Answer:</h2>

B. 12/5

<h2>Step-by-step explanation:</h2>

In a division, we should swap the second fraction and change the equation to times. After that, we can multiply each fraction easily.

4/5 : 1/3

= 4/5 x 3/1

= 12/5

In conclusion, the simplified quotient of 4/5 : 1/3 is 12/5

Area of a square is 196 cm²

andrew-mc [135]

Step-by-step explanation:

Area of Square=side²

Side=√(Area of the square)

Given area of the square=196cm²

Side of the square=√196=14cm

Perimeter of square=4*side=4*14=56cm

Length of the rectangle=(14+x)cm

Breadth of the rectangle=(14-y)cm

Area of rectangle=Length*Breadth=

(14+x)(14-y)=14(14)+14(-y)+x(14)+x(-y)=(196-14y+14x-xy)cm²
