You could line them up 12! (12 factorial) ways.
12*11*10*9*8*7*6*5*4*3*2*1

It might be <span>479001600 or 12 factorial... I may be wrong. 
So like
12*11 for the first slot
12*10 for the 2nd slot
and so on.</span>

The area of the rectangle as a single expression
Ne4ueva [31]

Answer: A=15x^2+6x-48

Step-by-step explanation:

The area of a rectangle can be calculated with this formula:

A=l*w

Where "l" is the length and "w" is the width.

You can identify from the figure that the length and the width of this rectangle are:

length=3(x+2)\\width=5x-8

Then, you need to substitute this lenght and this width into A=l*w:

A=3(x+2)(5x-8)

Now, apply Distributive property:

A=(3x+6)(5x-8)\\\\A=15x^2-24x+30x-48

Finally, you need to add the like terms. Then, you get:

A=15x^2+6x-48

Someone solve these equations with working really appreciate it
nignag [31]

Answer:

a) t = \sqrt{\frac{d}{4.9} }

b) t = 0.3 seconds

c) d = 4.9t²

d) d = 11 cm.

Step-by-step explanation:

One test involves catching a 1 m ruler and measuring the distance, d in meters, that the ruler will travel before being caught, the reaction time t in seconds is then calculated using the formula

t = \sqrt{\frac{2d}{9.8} } .......... (1)

a) the simplified expression is

t = \sqrt{\frac{d}{4.9} } ......... (2)

b) If d = 44 cm = 0.44 meters, from equation (2) we get,

t = 0.299 seconds ≈ 0.3 seconds (Approximate)

c) If we make d as the subject of the equation, then

t^{2} = \frac{d}{4.9}

⇒ d = 4.9t² .......... (3)

d) Now, if t =  \frac{0.3}{2} = 0.15 seconds, then from equation (3) we get,

d = 4.9 (0.15)² = 0.11 meters = 11 cm (Answer)
