Answer:

l = 12

Step-by-step explanation:

Let l = length

width = l+9

The area of rectangle is

A = lw

A = l * (l+9)

252 = l^2 +9l

Subtract 252 from each side

0 = l^2 +9l -252

Factor

What 2 numbers multiply to -252 and add to 9

21*-12 = 252

21-12 = 9

0 = (l+21) (l-12)

Using the zero product property

l+21=0    l-12=0

l = -21     l = 12

We cannot have a negative length

l = 12

A bag contains 6 red tiles, 8 blue tiles, and 6 green tiles. A tile is drawn, the color recorded, and then the tile placed back
tester [92]

Answer:

9 red tiles


Step-by-step explanation:


Total number of tiles: 6+8+6=20

Total number of red tiles: 6


Probability of getting red in one draw:  \frac{6}{20}=0.3

<em>This means that you would expect to get red 0.3  or 30% of the times.</em>

<em>Hence, when you draw tiles 30 times from the bag, you would expect red to be picked 30% of 30 times. This is:</em>

<em>0.3*30=9</em>

So, you would expect to draw a red tile from the bag 9 times.
