Answer:
The correct option is;
Use a scale factor of 2
Step-by-step explanation:
The parameters given are;
A = (1, -6)
B = (5, -6)
C = (6, -2)
D = (0, -2)
A'' = (1.5, 4)
B'' = (3.5, 4)
C'' = (4, 2)
D'' = ( 1, 2)
We note that the length of side AB in polygon ABCD = √((5 -1)² + (-6 - (-6))²) = 4
The length of side A''B'' in polygon A''B''C''D'' = √((3.5 -1.5)² + (4 - 4)²) = 2
Which gives;
AB/A''B'' = 4/2 = 2
Similarly;
The length of side BC in polygon ABCD = √((6 -5)² + (-2 - (-6))²) = √17
The length of side B''C'' in polygon A''B''C''D'' = √((4 -3.5)² + (2 - 4)²) = (√17)/2
Also we have;
The length of side CD in polygon ABCD = √((6 -0)² + (-2 - (-2))²) = 6
The length of side C''D'' in polygon A''B''C''D'' = √((4 -1)² + (2 - 2)²) = 3
For the side DA and D''A'', we have;
The length of side DA in polygon ABCD = √((1 -0)² + (-6 - (-2))²) = √17
The length of side D''A'' in polygon A''B''C''D'' = √((1.5 -1)² + (4 - 2)²) = (√17)/2
Therefore the Polygon A B C D can be obtained from polygon A''B''C''D'' by multiplying each side of polygon A''B''C''D'' by 2
The correct option is therefore;
Use a scale factor of 2.
6 x 7 + 9 x 7
Explanation:
Ok so if you separate that figure into two shapes, you will have 2 rectangle.
Its kinds too long to explain, but just know that to find the formula of a rectangle is length x width.
So, find the area of the rectangle on the left first:
The width of the rectangle on the left is 6
The length is 7
Multiply 6 x 7
Next, find the area of th rectangle on the right:
The length is 9
The width is 7
Multiply 9 x 7
Since this is originally one figure, we do this:
6 x 7 + 9 x 7

Answer:
11/35
Step-by-step explanation:
There are a total of 21 people in the group, 12 of whom are not Democrats. The members are selected in succession. The probability the first member isn't a Democrat is 12/21.
Now there are 20 people remaining, 11 of who are not Democrats. So the probability the second member isn't a Democrat is 11/20.
The total probability is (12/21) (11/20) = 11/35
