Answer:
![B''C''=3BC](https://tex.z-dn.net/?f=B%27%27C%27%27%3D3BC)
Step-by-step explanation:
we know that
The length of segment B''C'' is equal to the length of segment BC multiplied by the scale factor
step 1
Find the length of segment BC
the formula to calculate the distance between two points is equal to
![d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28y2-y1%29%5E%7B2%7D%2B%28x2-x1%29%5E%7B2%7D%7D)
we have the points
B(1,-3),C(-3,-3)
substitute the values
![BC=\sqrt{(-3+3)^{2}+(-3-1)^{2}}](https://tex.z-dn.net/?f=BC%3D%5Csqrt%7B%28-3%2B3%29%5E%7B2%7D%2B%28-3-1%29%5E%7B2%7D%7D)
![BC=\sqrt{(0)^{2}+(-4)^{2}}](https://tex.z-dn.net/?f=BC%3D%5Csqrt%7B%280%29%5E%7B2%7D%2B%28-4%29%5E%7B2%7D%7D)
![BC=4\ units](https://tex.z-dn.net/?f=BC%3D4%5C%20units)
The segment B''C'' is equal to the segment BC multiplied by the scale factor
The scale factor is 3
so
![B''C''=BC(3)](https://tex.z-dn.net/?f=B%27%27C%27%27%3DBC%283%29)
![B''C''=3BC](https://tex.z-dn.net/?f=B%27%27C%27%27%3D3BC)
substitute
![B''C''=3(4)=12\ units](https://tex.z-dn.net/?f=B%27%27C%27%27%3D3%284%29%3D12%5C%20units)
Answer:
C, None of the above
Step-by-step explanation:
Step 1: Expand the brackets
-7 - 3(-4e-3)
-7 + 12e + 9
Step 2: Collect like terms
12e + 2
Because the answer is not a or b the answer is 'None of the Above'
Answer:
C
Step-by-step explanation:
Answer:
Your answer would be 36
Step-by-step explanation:
You can figure this out by multiplying B by C to get A or
4 x 9 = 36
Then you can check by going
36 ÷ 4 = 9
9 = 9
This is the right answer
